# Parallel Circuit — AP Physics 2 Definition & Exam Guide

## Definition

A parallel circuit is a circuit where the components are connected side by side, providing separate paths for current flow.

### Related Terms

- [Kirchhoff's Current Law (KCL)](/ap-physics-2-revised/key-terms/kirchhoffs-current-law-kcl): KCL states that at any junction point in an electrical circuit, the sum of currents entering that point must be equal to the sum of currents leaving that point.
- Equivalent Resistance: In a parallel circuit, equivalent resistance is calculated differently than in series circuits because there are multiple paths for current flow.
- Power Dissipation: Power dissipation refers to how much power is lost or converted into heat as electric energy passes through resistive elements in a parallel circuit.
