• C. Electric cell
• D. Electric motor

Answer 1

Answer: (A), (B), (D)

The correct options are
A

Electric bell

B

Electric fan

D

Electric motor

Except for an electric cell, all other appliances i.e. a bell, a motor, and a fan uses an electromagnet as one of their important components. Without using an electromagnet one cannot make a bell ring, a fan to rotate or a motor to turn. Using this, one converts electrical energy into kinetic energy or sound energy. A cell comprises of a fused chemical enclosed in a small metallic cylinder with two terminal points at both the ends.
