Electricity, who learns it well, how to learn it well

Why is electricity a headache for so many people? Because electricity is relatively abstract, some problems can only be imagined, and circuit diagrams have high requirements for thinking skills, so many people fall into the pit.

First of all, you need to do a good job of pre-studying, understanding the basic concepts, such as the meaning of electricity, especially the circuit diagram to read several times.

When you are in class, you should listen carefully to the class, especially when the teacher is doing experiments, you should study seriously, and you can also ask the teacher to borrow experimental instruments to do experiments for you after class, so as to enhance your practical ability.

Do more exercises, although the tactics of the sea of questions are not advocated, but the science subjects need to be practiced more, so that they can be more flexible. Remember, it is very important to preview and summarize, after the preview, do the questions yourself, and then summarize some methods, such as what is the reason why the light bulb does not light up, you should memorize it, because you often take the test, and you also know how to measure.

Believe in yourself and don't be discouraged, it's not hard now. It's not until you're in the third year of junior high school that you learn about electricity, and you don't have to think about it if you don't drive you crazy.

As long as you do a good job of pre-studying, it is not so difficult to summarize often, and it is better for you to be one or two lessons ahead of the teacher.

Hello, pls how can I help.

Dynamic circuits in junior high school electricity are a big difficulty, and many students have a headache about this part, in fact, there are some tips here.

Tools Raw materials.

Textbooks, scratch paper correction books.

Method steps.

1 3 Step by Step Reading.

The first step is to understand the circuit diagram, the connection method of each component, which electrical appliance is measured by each meter, and the change in resistance of the sliding rheostat, which can be simply recorded on scratch paper.

2 3 The second step is to find out the original that causes the change of the circuit, judge whether it makes the total resistance in the circuit larger or smaller (can be calculated according to the equivalent resistance), and then judge the change of the total current of the circuit, and then analyze the change of the current and voltage of the fixed resistance in the circuit (according to Ohm's law), and finally analyze the change of the current and voltage of the resistance that causes the change of the circuit (according to the current and voltage characteristics of series and parallel).

3 3 In the third step, the answer can be obtained by matching the physical quantities that need to be judged with the physical quantities judged in the second step.

Precautions. This kind of question should pay attention to the power supply voltage in the question generally does not change, if it changes, the second step should be specific to the specific situation.

Understand the history of development, use celebrities as examples to motivate yourself, read more books and practice, communicate with peers, and worship those who can be teachers.

One is to understand the concept of objects. Physics studies place special emphasis on learning methods and cannot be memorized. Physics is different from other disciplines in that there are many concepts, principles and formulas, which are scientific abstractions, and some electrical concepts and principles are far away from life and appear particularly abstract, such as electric fields, electric potentials, electric field lines, voltages, etc.

Therefore, for conceptual and principled knowledge, it is emphasized to understand, understand the differences and connections between their definitions, meanings, properties, units, and concepts, and form memories on the basis of understanding. Second, it is necessary to master the application of formulas. For formulas, it is emphasized that they should know how to apply, and on the basis of understanding the meaning and scope of application of relevant formulas in electricity, they should be able to solve problems according to the correct steps (knowing, solving, solving, and answering), and they should practice more to achieve proficiency.

We know that in our real life, electricity is very extensive. Because no matter what, you need to use electricity. So, it's a very specialized knowledge.

Naturally, for us, if we can master his knowledge, then you will be able to have a better development. So about electricity, it should be best to start with **? Personally, I think it starts from life.

In our lives, there is a lot of similar knowledge related to electricity. These things are also very familiar to us. So we're going to have a lot of interest as well, so it's going to be easier for us to get started.

So for us, electricity starts from the basics, from life. It can be more handy, it can be simpler. Of course, it is very dangerous for us to figure it out on our own.

We should learn through this method, and let's take a brief look at it together. <>

First of all, learn from a professional master. We know that in real life, there are a lot of similar professional electricians. They may not have deep theoretical knowledge, but they know how to deal with it.

Therefore, for us, learning from them can quickly improve our theoretical knowledge. This is very beneficial for our own development. <>

Secondly, theoretical learning. If you only know the practical things and do not know the theoretical things, then there is no use. So, we still need to understand some theoretical knowledge.

Of course, there are many ways to do this. We can do it online, but we can also use books. In this way, we can quickly absorb this theoretical knowledge and provide it for our reference.

I hope you will pay attention to it, because these things are important to us. Only when we pay attention to it, can we truly change this image and better improve ourselves. So, since it's good for us, then we're going to fight for it, so go and give it a try, and I'm sure there will be an improvement

I think you should start with some basics, because electricity is a very profound science, so you should start from the basics so that you can understand it.

It should be learned from the beginning, so that we can understand the content of electricity, and it can also help us learn better.

We should first understand electricity and start learning, so that we can understand electricity better and make us proficient in learning.

The following two majors in the power industry are better than confession:

1. Training objectives of power plants and power systems: to cultivate advanced engineering and technical application talents who are engaged in electrical design, operation, maintenance, management and installation, commissioning and overhaul of electrical equipment related to power generation systems, transmission systems, power supply and distribution systems in modern power plants, power systems, industrial and mining enterprises and institutions. Through the study of the basic theories and professional knowledge necessary for this major, students receive practical training in engineering, and have the professional ability and professional quality to engage in the design, operation and maintenance, installation and commissioning and technical management of power plants and power systems.

2.The training goal of power supply technology: to cultivate advanced engineering and technology application talents who are engaged in electrical design, operation, maintenance, management and electrical equipment related to the dismantling system and power system of power supply and distribution system, as well as the installation, commissioning, maintenance, power monitoring and business management of power distribution station electrical equipment in power supply enterprises, industrial and mining enterprises and institutions.

Students will learn and master the basic theory of power supply and distribution system, electrical equipment, normal operation of power system, fault handling, power supply and consumption, production management, business management and other aspects of professional knowledge, and receive practical engineering training. Hope it helps.

In junior high school, I didn't think it was difficult to learn mechanics or electricity. Compared with high school, it is a kindergarten problem, in fact, you don't have much exposure to physics, junior high school physics does not involve vector operations, so many problems and many phenomena are not explained in the textbook, for example, you study mechanics, but have you ever thought about what is the relationship between motion and force, why does an object move, what is its motivation?

In junior high school, electricity and mechanics are completely separated, there is no connection, so you don't have to worry about the basics, basically you just need to listen to the lectures, do a good job, pay special attention to several important experiments in electricity, very important laws, as long as you master these laws, you will be handy in the practice of electricity, and there will be no problem in the high school entrance examination.

In high school, mechanics is the foundation of the study of physics, and you can continue to study whether it is heat or electricity, so I suggest that you learn more mechanics in junior high school and practice force analysis of objects. This is important, very important.

Finally, you have to be confident that your learning is easy, and the difficulty of physics questions in high school can make people jump off buildings. You won't.

Do the exercises, and ask for the kind of questions that have a detailed explanation. If you do more, your understanding of electricity will be deepened, and the questions in the exam are all at these levels, you do it, remember it, and you can cope with it.

Understanding is the foundation, and then do more and compare.
