Question

coulomb is a very large unit for practical use. Justify this statement, if 10^10 electrons are transferred from a body per second

Answer 1

charge on one electron is 1.69*10^-19 coulombs now if you talk about 10^10 electrons per second that means total charge would be 1.69*10^-9 coulomb which is a huge amount of charge....to store such amount of charge you need a huge capacitor ..in just one second 10^10 electrons are transferred so in an hour you can estimate how much electrons will flow...and may be we don't have such a big capacitor to store that much charge
