5. What number of electrons will flow in one minute through a conductor that carries 1 Ampere current? a) 5.2*1020 b) 4.2*1020 c) 3.7*1020 d) 3.7*1019
Answer: c Explanation: 1 Ampere means 1 Coulomb per second. So the number of electrons flow per second is (11.602∗10−19). Therefore number of electron flow in one minute =11.602∗10−19*60 =3.7*1020.The number will be 60 times more if we have to calculate the number of electron flow in an hour.
