Question

how many electrons are there in one column of charge

Answer 1

A coulomb of electron charge is equal to the the charge of 6.241509324×10 18electrons.

Answer 2

in 1columb of charge
Q=ne
A single electron has a charge of 1.60217733 × 10-19 Coulombs. A collection of 6.2415 × 1018 electrons has a charge of one Coulomb (1/1.60217733x10-19). 1.6 into 10 raise to power -19 no of electrons are present in one coulomb of charge.
