What is continuous charge distribution ?

Shrishti Agrawal 7 years, 5 months ago

Continuous charge distribution is distribution of charge uniformly to an entire body of the system

1Thank You

Avishek Chatterjee 7 years, 5 months ago

it is very impractical to consider charge distribution of a body in terms of location of microscopic charges . So to have the distribution more accurate we consider charge as a continious distribution over the whole surface of the body . best refer to NCERT PHYSICS PART 1 PG 32
