Symbol A . . . . . a battery

Symbol B . . . . . a light bulb

Symbol C . . . . . a switch that turns the light bulb on and off.  The switch is 'open' in the diagram, so no current is flowing anywhere in the circuit, and the light bulb is not glowing.

Explanation:

According to diagram,

Symbol B shows the bulb.

Symbol A shows the battery

Symbol C shows the key.

The key is open in the diagram so the current is not flowing in the circuit and the bulb will not glow.

If the key is closed then the current will flow in the circuit and the bulb will glow.
