What are the classifications of circuits and the composition of circuits?

It is necessary to divide strong current and weak current into threading separately.

1.The composition of the circuit: the power supply, the electrical appliance, the switch and the wire are composed of four parts, the lack or incompleteness will affect the normal operation of the circuit.

2.The role of each part of the circuit.

Component. Function.

Common devices. Power supply.

A device that provides electrical energy and converts other forms of energy into electricity.

What is a circuit.

A circuit is a whole that is connected by various components (or electrical equipment) in a certain way, that is, a path that provides a loop for the flow of current.

The basic composition of an electrical circuit.

1.Power supply. A power supply is the component that provides energy to an electrical circuit.

In daily life, household appliances are mostly powered by mains voltage, while doorbells, flashlights and other electrical appliances are powered by dry batteries, so people usually refer to mains voltage or dry batteries as power sources. In the actual circuit, devices such as storage batteries, dry batteries, and generators can supply power to the load, so they are all power sources.

In practical application, there are two kinds of power supply: AC and DC, the battery and dry battery are DC power sources, and the mains voltage and alternator are AC power sources.

2.Load. A load is a device or device that uses (consumes) electrical energy, such as an electric motor, heater, lamp, etc.

In practical application, for the mains voltage, household appliances such as lights, televisions, washing machines, refrigerators and so on are its loads; In the case of a flashlight, the bulb is the load of the dry battery.

3.Control devices.

A control device is a device or device that controls the working state of the circuit, such as switches, leakage protectors, etc. In practical application, the switch is the control device of the lighting circuit, and the switch linked in the button of the rice cooker is the control device of the rice cooker circuit.

4.Conducting wire. The function of the wire is to connect the electrical equipment or components in a certain way (such as various copper, aluminum cables, etc.). In practical applications, the lighting wire is the wire of the lighting circuit, and the shell of the flashlight is also a special wire.

Prompt. In a circuit, a wire is not only a wire that provides a circuit, but also a connected switch, diode, inductor, and other components that are turned on, making the circuit simple and straightforward.

Components of the circuit: The circuit is composed of four parts: power supply, switch, connecting wire and electrical appliance. The various devices that use electrical energy in a circuit are collectively referred to as loads.

The function of the load is to convert electrical energy into other forms of energy. For example, an electric furnace converts electrical energy into heat; Electric motors convert electrical energy into mechanical energy, and so on. ”

Circuit: It is a closed circuit composed of power supplies, wires, switches, and electrical appliances. Among them, the power supply:

provision of electrical energy; Wire: Transmission of electrical energy; Switch: control the switching on and off of circuits or electrical appliances; Electrical appliances:

Electricity is consumed. The loop through which the current flows is called a circuit, also known as a conductive loop. The simplest circuit is composed of power supply, electrical appliances (loads), wires, switches and other components.

The circuit consists of the following:

1. a power supply; 2. a wire;

3. a switch; 4. Electrical equipment.

The circuit is composed of four parts: power switches, connecting wires, and electrical appliances. Various devices that make electricity in a circuit are collectively referred to as negative. Negative work converts electricity into its formal quantity. For example, an electric furnace converts electricity into heat, an electric motor converts electricity into machinery, and so on.

Circuits generally consist of power supplies, wires, switches, and electrical appliances.

The circuit is connected by electrical equipment and components, in a certain way, to provide the overall path for the flow of charge, and the power supply circuit refers to the circuit design of the power supply part of the power supply provided to the electrical equipment, and the circuit form and characteristics used.

The power supply is both AC and DC.

The types of circuits mainly include the following: analog circuits.

The continuous physical natural quantities generated by nature are called analog circuits when the continuous physical natural quantities are converted into continuous electrical signals, and the circuits that calculate the continuous electrical signals are called analog circuits.

Analog circuits process the continuous voltage and current of electrical signals.

The most typical analog circuit applications include amplification circuits, oscillation circuits, and linear operation circuits.

Calculate continuous electrical signals.

Electronic circuits. Depending on the signal being processed, electronic circuits can be divided into analog circuits and digital circuits.

Digital circuits. It is a circuit that converts a continuous electrical signal into a discontinuous quantitative electrical signal and calculates the discontinuous quantitative electrical signal.

In a digital circuit, the signal size is a discontinuous and quantified voltage state.

Most Boolean algebraic logic circuits are used to process the quantified signal.

Typical digital circuits include registers, adders, oscillators, subtractors, etc., to calculate discontinuities and quantitative electrical signals.

The types of circuits mainly include the following: analog circuits, amplification circuits, oscillation circuits, and linear operation circuits. Calculation of continuous electrical signals and electronic circuits.

Add a power supply to the input of the circuit to create a potential difference at the input terminal, and it can work when the circuit is connected. The presence of current can be detected by some instruments, such as voltmeter or ammeter deflection, bulb light, etc.;

According to the nature of the current flowing, it is generally divided into two types: the circuit through which direct current passes is called "DC circuit", and the circuit through which alternating current passes is called "alternating current circuit".

It depends on what type you divide it into?

From the connection mode, it can be divided into series, parallel, and mixed connection (also called series-parallel). Bridges cannot be placed alongside these three categories.

There are many other ways to divide it, such as high-frequency circuits, low-frequency circuits. Digital circuits, analog circuits, and much more.

To put it simply: three.

Series circuits, parallel circuits, hybrid circuits.

The types of circuits are as follows: Answer.

2. Computer circuits, which are advanced circuits for microprocessor circuits, forming desktop computers, notebook computers, handheld computers, industrial computers, various computers, etc.;

4. Display circuit, forming various displays such as screens, TVs, instrument drafts, etc.;

5. Photoelectric attack on filial piety, often using light energy to generate electricity, such as solar circuits;

6. Motor circuits are often used in large power supply equipment, such as power equipment, transportation equipment, medical equipment, industrial equipment, etc.

Tandem hood circuit and parallel circuit:

1. The series circuit refers to the circuit in which the lead current passes through each component in turn, and the current flowing through each resistance in the series circuit is equal, because each section of the same branch in the DC circuit has the same current intensity;

2. The parallel circuit is a connection mode between components, which is characterized by connecting two components and devices of the same or different classes, and at the same time, the tail and tail are also connected, which is usually used to refer to the connection mode of electronic components in the circuit.
