- The circuit is incomplete; the bulb will not light because there is no closed loop for the current to flow from the battery through the bulb and back.
- The circuit is complete; the bulb will light as current can flow in a closed loop from the battery, through the bulb, and back to the battery.
- The circuit is incomplete; the bulb will not light because the switch is open, breaking the path for current flow.
- The circuit is complete with two bulbs in parallel; both bulbs will light as each has its own path for current from the battery.
- The circuit is incomplete; the bulb will not light because the switch is open, preventing current from flowing through the circuit.
- The circuit is complete with two bulbs in series; both bulbs will light as current flows through one bulb, then the other, in a single path from the battery.
