What is a Parallel Circuit?

Parallel circuit: A parallel circuit is one of two basic ways to make the circuit have more than one independent path between the currents that constitute the parallel circuit elements.

Definition: use

The total voltage across the series circuit is equal to the sum of the voltages across the consumers.

That is: U = U1 + U2

U1: U2: U3 = IR1: IR2: IR3 = R1: R2: R3

P1: P2: P3 = IU1: IU2: IU3 = R1: R2: R3

Characteristics of the series circuit:

1. There is only one path for current.

2. The switch controls the on and off of the entire circuit.

3. Electric appliances interact with each other.

4. Series circuit currents are equal everywhere: Itotal = I1 = I2 = I3 = ... = In

5. The total voltage of the series circuit is equal to the sum of the voltages everywhere: U = U1 + U2 + U3 + + Un

6. The equivalent resistance of the series resistance is equal to the sum of each resistance: R total = R1 + R2 + R3 + ... + Rn

7. The total power of the series circuit is equal to the sum of the powers: P total = P1 + P2 + P3 + ... + Pn [derivation: P1P2 / (P1 + P2)]

8. The inverse of the equivalent capacitance of the series capacitor is equal to the sum of the inverse of the capacitance of each capacitor: 1 / Ctotal = 1 / C1 + 1 / C2 + ... + 1 / Cn

9. In a series circuit, except that the currents are equal everywhere, the other physical quantities are proportional to each other (the series circuit is also called a voltage dividing circuit): (the work done by the current refers to the size of the same time during the power-on) P1: P2 = W1: W2 = Q1: Q2.

10. The switch controls the entire circuit at any position, that is, its function has nothing to do with the position. There is only one path for current, and the current through one lamp must pass through the other. If one lamp is turned off, the other lamp must be turned off.

11. If you want to control all the circuits in one circuit, you can use a series circuit.

12. In a series circuit, as long as it is disconnected at one point, the entire circuit becomes open. That is, the electronic components connected in series cannot work normally. ^[1]

    Definition: A parallel circuit allows more than one current to flow between circuit elements that make up a parallel circuit.

    1. The voltages of the branches in the parallel circuit are equal and equal to the power supply voltage.

    1. Regardless of whether it is a series circuit or a parallel circuit, the total power consumed by the circuit is equal to the sum of the power consumed by each consumer. W = W1 + W2.

    2. Regardless of whether it is a series circuit or a parallel circuit, the total electric power of the circuit is equal to the sum of the electric power consumed by each electrical appliance. P = P1 + P2.

    3. The sum of the total electric heat generated by a series circuit or a parallel circuit and the electric heat generated by various electrical appliances. Q = Q1 + Q2. ^[1]
