A 6-V battery powers a circuit with parallel branches on a board. Several wires and light bulbs plug into the board to make various series and parallel circuits. The brightness of the bulbs changes ...

Figure caption, A series circuit with two bulbs and one cell ... all the lights would go out if one breaks. In a parallel circuit, measurements of the current at different points in the circuit ...

A parallel circuit is way of connecting components on separate branches, so the current can take different routes around the circuit. The current is different in different parts of a parallel circuit.
