Answer 2

Answer:

• The first reason for the bulb to glow in the above circuit, the switch has to be in the on position and not its own off position.
• The electric switch is the device that breaks or completes the ‘circuit’ and the ‘current flowing’ through the circuit.

• The second reason might be a ‘break in the fuse’ or the ‘filament of the bulb’ which might break the path of the current flowing in the circuit.
