3.10 If a current of 0.5 ampere flows through a metallic wire for 2 hours, then how many electrons would flow through the wire?
Answers (1)
Firstly we will find total charge flown through the wire then we will calculate number of electrons.
We are given :- I = 0.5 A, Time = 2 hours = 7200 seconds.
We have, Q = I.t
= (0.5)7200 = 3600 C.
Now we will convert charge into number of electrons.
We know that
So toal number of electrons :
or no. of electrons will flow through wire.
