Question

In the case of an electric cell, the armature is connected to a hammer made of plastic.

• A. True
• B. False

Answer 1

The correct option is B False

1. In the case of an electric bell, the armature is connected to a hammer made of steel.
2. When the switch of the electric bell is “on”, the electric current flows through the coil of the electromagnet, and the electromagnet starts behaving like a magnet.
3. The electromagnet due to its attractive property starts attracting the armature.
4. When the armature moves towards the electromagnet, the steel hammer connected to it hits the steel gong, and sound is produced.
5. Plastic hammer on hitting the gong cannot produce a loud audible sound and consequently, a plastic hammer cannot be used as a hammer in an electric bell.
6. Below is the diagram showing the hammer, gong, and other components of an electric bell.

Hence, the given statement is false.
