How do you connect in series and in parallel? What is series and parallel?

The difference between series and parallel: if the components in the circuit are connected one by one, the circuit is a series circuit, and if the components are connected in parallel between the two points of the circuit, the circuit is a parallel circuit. The features are as follows. Series circuits:

The current of the series circuit is equal everywhere: i total. i1

The total voltage of the I2i3IN series circuit is equal to the sum of the voltages everywhere: U total = U1 + U2 + U3 + ......The equivalent resistance of the un series resistor is equal to the sum of the resistors: r total = r1 + r2 + r3 + ......The total power of the rn series circuit is equal to the sum of the powers:

P total = P1 + P2 + P3 + ......The reciprocal of the equivalent capacitance of the PN series capacitor is equal to the sum of the reciprocal capacitance of the individual capacitors: 1 C total = 1 C1 + 1 C2 + ......1/cn

Parallel connection. 1. The components in the combination have the same voltage: u1 = u2 = u3 = ......=un2, the current flowing into the combined endpoint is equal to the sum of the currents flowing through several elements: i total. i1i2i3

+in3, the reciprocal of the equivalent resistance of the parallel resistor is equal to the sum of the reciprocals of each resistor:

1/r=1/r1+1/r2+1/r3+……1/rn；

For example, every room in your home has a switch for a light, and when one of the switches is closed and disconnected, it has no effect on the lights in the other rooms. That is to say, these lights in your home are all in parallel (as shown in the diagram I attached, it can be seen that S1 and S2 control two different lights).

The series connection is just the opposite, suppose your lights are all connected in series, just press a switch, all the lights will be on, and then press it will be off.

Hope it solves your problem.

Tandem:

Series connection is one of the basic ways to connect circuit components. Connect the circuit components one by one, one after the other. The circuit composed of connecting various electrical appliances in series is called a series circuit.

In a series circuit, the current through each consumer is equal.

Parallel connection.

Parallel connection 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. It is usually used to refer to the way in which the electronic components in a circuit are connected, that is, parallel circuits.

Features of series and parallel circuits:

In a series circuit, since there is only one path of current, the current flowing from the positive terminal of the power supply will flow through each consumer one by one and finally back to the negative terminal of the power supply. Therefore, in a series circuit, if one of the consumers is damaged or disconnected somewhere, the whole circuit will become open, the circuit will be free of current, and all the appliances will stop working.

Therefore, in a series circuit, several electrical appliances are implicated in each other, and either all work or all stop working. In a parallel circuit, the current flowing from the positive terminal of the power supply is divided into two branches at the branches, each with current flowing through it, so that even if one branch is disconnected, the other branch will still form a path with the trunk circuit. It can be seen that in a parallel circuit, the branches are not implicated with each other.

First, the voltage is different1. Series connection: The total voltage at both ends of the series circuit is equal to the sum of the voltages at both ends of each part of the circuit.

2. Parallel: The voltage at both ends of each branch of the parallel circuit is equal.

Second, the current is different1. Series connection: The current is equal everywhere in the series circuit.

2. Parallel: The current of the trunk circuit in the parallel circuit is equal to the sum of the currents of each branch.

Third, the resistance is different1. Series connection: The total resistance of the series circuit is equal to the sum of the resistance of each series conductor.

2. Parallel: The reciprocal of the total resistance of the parallel circuit is equal to the sum of the reciprocal of the resistance of each parallel conductor.

To use an analogy, parallel connection is when you go to a junction and have multiple forks, but they can all reach their destination, that is, they all go to the same destination. In series, it is you who go all the way to the dark, and you can't turn back if you hit the wall.

To put it in layman's terms, tandem is mainly understood"Skewers"To give a simple example, the current is like a river, a river only flows along one route, then the branch road can be regarded as a series, if the river flows along two branches, and then merges with one, then these two branches can be regarded as parallel...

1. The series connection is connected from end to end, and the parallel connection is equal connection.

2. The same current passes through A and then through B in turn, and Ganga A and B are connected in series.

One current passes through A, and the other current passes through B, and these two currents later flow to the same wire, and A and B are connected in parallel.

Quite simply, if it is connected in series, only one point of the two parts of the circuit is directly connected, and if it is connected in parallel, one point at each end is directly connected, if it is not, it is neither in series nor in parallel.

Note: If there are branches at the connected points in the concatenation judgment, it is not concatenation.

I divide it like this, the series circuit is a line that comes out of the positive pole of the power supply, and returns to the negative pole through electrical appliances; In the parallel circuit, after coming out of the positive pole of the power supply, it is divided into several branches, and then returns to the negative pole after passing through the electrical appliance.

Parallel and series connection of resistor series.

With the equivalent node method! Guaranteed you won't make a mistake! The specific method is too many words, you can ask your teacher to highlight it for you!

1. The difference between series and parallel.

1. The connection method is different.

Series connection refers to the connection of circuit components (such as resistors, capacitors, electrical appliances, etc.) one by one. In a series circuit, the current through each consumer is equal. Parallel connection is a connection method that connects two components and devices of the same or different kinds, and at the same time, the tail is also connected.

It is usually used to refer to the way the electronic components in a circuit are connected.

2. The current and voltage paths are different.

In a series circuit, the current has only one path, the total voltage of the series circuit is equal to the sum of the voltages at all places, and the equivalent resistance of the series resistance is equal to the sum of the resistors. In parallel circuits, there are several paths in the circuit, and the voltages are equal everywhere in the parallel circuit.

3. The impact of the most switch on the line is different.

The switch in series controls the on/off of the entire circuit. Parallel connection means that the trunk switch controls all the electrical appliances, and the branch switch controls the electrical appliances of the branch where it is located.

2 series circuits.

Definition: Series connection is one of the basic ways to connect circuit components. Circuit components (such as resistors, capacitors, inductors, electrical appliances, etc.) are connected one by one.

The circuit composed of connecting various electrical appliances in series is called a series circuit. In a series circuit, the current through each consumer is equal.

Features: There is only one path in the circuit, and any open circuit will appear open.

3. Parallel circuits.

Definition: Parallel connection is a connection method between components, which is a connection method that connects two components and devices of the same or different classes, and at the same time, the tail and tail are also connected. It is usually used to refer to the way in which the electronic components in a circuit are connected, that is, parallel circuits.

Features: The circuit has multiple paths, each circuit is independent of each other, one circuit component is open, and the other branches work as usual.

The difference between series and parallel connection is that current, voltage, and resistance are calculated differently.

1. The calculation of series and parallel currents is different.

The current is equal everywhere in a series circuit. In a parallel circuit, the current of the trunk circuit is equal to the sum of the currents of each branch.

2. The calculation of series and parallel voltage is different.

The total voltage at both ends of the series circuit is equal to the sum of the voltages at both ends of the circuit part. The voltage at both ends of each branch of the parallel circuit is equal.

3. The calculation of series and parallel resistance is different.

The total resistance of a series circuit is equal to the sum of the resistances of the various series conductors. The reciprocal of the total resistance of the parallel circuit is equal to the sum of the reciprocal of the resistance of the individual parallel conductors.

Parallel and series connection are two common connections in circuits, and they play an important role in the installation and use of electronic components.
