Question

Consider a simple circuit, such as a light bulb connected to a battery. Which statement is correct?

The current passing through the battery is smaller than that passing through the light bulb since some is used up in the battery.

Current only flows through the light bulb and connecting wires, not through the battery.     

The current passing through the battery is smaller than that passing through the light bulb since some is used up in the light bulb.

Since the current must flow in a continuous loop, the current through the battery is the same as the current through the light bulb.

Explanation / Answer

Since the current must flow in a continuous loop, the current through the battery is the same as the current through the light bulb.
