Question

calculate number of electrons and amount of charge flowing through a conductor for 10 seconds when a current 20 ampere flows from it

Answer 1

Answer:we know I=Q/T

Where I is current Q is Amount of charge and T is time

I =20ampere

T is 10s

So by formula Q is 200Columb(amount of charge)

Now we know 1columb is equal to 1.6×10^-19electons

Now of electons are 20×1.6×10^-19

=3.2×10^-18
