Current and circuits
Lower Sec Science · Secondary 2 · Medium · Current and circuits
A student connects a bulb, a switch and a battery in a circuit. The bulb does not light even though all components work. Which statement best explains why the bulb does not light?
- The circuit is not a closed loop, so current cannot flow through the bulb.
- The bulb has too high a resistance, so no current can ever flow.
- The battery produces voltage but no current in any circuit.
- The switch must always be placed directly next to the bulb to work.
