Question

Why can one ignore quantization with electric charge while dealing with macroscopic?

Answer 1

We can ignore the quantization of electric charge when dealing with macroscopic charge because the charge on one electron is 1.6×10−19C in magnitude , which is very small as compared to the large scale changes.

Answer 2

Answer:

In practice, the charge on a charged body is very small. On the other hand, the charge on the electron is very small.

When electrons are added to a body or removed from a body, the change taking place in the total charge on the body is so small that the charge seems to be varying in a continues manner.

Therefore, the quantization of electric charge can be ignored, when dealing with a large scale charged body.
