Question

Sometimes a crackling sound is heard while taking off a sweater during winters. Explain.​

Answer 1

Answer:

Sweaters are made up of wool , which is a poor conductor of electricity. When we are wearing the sweater the wool is in contact with our body, there is friction as there is rubbing between the body and the wool. ... due to this force, we hear the crackling sound while taking off the sweater during winters.
