Answer 1

Explanation:

1. Electromagnets are very widely used in electric and electromechanical devices, including:

(i) Motors and generators.

(ii) Transformers.

(iii) Relays.

(iv) Electric bells and buzzers.

2.An electric bell is a mechanical or electronic bell that functions by means of an electromagnet.

3.Most of the circuit components in the model are common electrical elements such as resistors, capacitors, and inductors.

4. An electric fuse is a safety device to prevent damage to an electrical circuit when excessive current flows through it.

5. When a current passes through a wire, a part of the electrical energy is converted into heat energy and the wire gets heated. This is known as heating effect of electric current. However in an electric bulb the filament gets hot which in turn glows and produces light. This is called lighting effect of electricity.
