Voltage and Current

Q1: The charge of one coulomb is equal to:

A 6.24 x 1018 electrons

B one second

C 6.24 x 10−18 electrons

D one ampere

ANS:D - 6.24 x 1018 electrons

The charge of one electron = 1.6 x 10^-19C

Therefore, to make a charge of 1C, we need 1/ 1.6 x 10^-19 = 6.25 6 x 10^18 electrons.
