For electricity to flow, what do you need?

Question

only a battery

B
only a battery and a light bulb

C
only a battery, light bulb and wire

D
a battery, light bulb and wire in a closed circuit

Answer 1

The correct answer is D: a battery, light bulb and wire in a closed circuit.

For electricity to flow, you need a complete pathway (closed circuit) for the current to travel through, which typically includes a power source (like a battery), a load (like a light bulb), and conductors (like wires) to connect them.
