I need the stepwise answer for the question 35
Q.35. How many electrons are flowing per second past a point in a circuit in which there is a current of 5 amp?

Dear student,
we know that ampere is equal to coulomb per second.
Charge of one electron =1.609x10^-19 C,
and
1A=1C/sec
So, 1C=1/1.609x10-19.
5A=5C/second
So, the number of electrons for 5amp current =5/1.609x10^-19=3.1075x10^19 electrons
Regards
