1.

Can you predict the reson for the bulb not glowing in situations 2 and 3 ?

Answer»

Solution :Yes, in situation 2 - there is no charge to travel in the CIRCUIT as the battery is DISCONNECTED. So, the BULB isn't glowing.
In situation 3, we REPLACED the copper wires with nylon wires. Nylon is not a conductor. So, the bulb isn't glowing.
