Current is a measure of how much electric charge flows through a circuit. The more charge that flows, the bigger the current. Current is measured in amperes. The symbol for ampere is A. For ...

Potential difference in parallel circuits. Quiz; Key points. A parallel circuit is way of connecting components on separate branches, so the current can take different routes around the circuit.

Series and Parallel Circuit Series and parallel circuits are two fundamental configurations in electrical circuits, each with distinct characteristics that affect how electricity flows through them.
