Question

in a conducting wire 6.25 ×11018 free electrons are flowing per second calculate the value of electric current in conductor (charge on electron e=1.6×10^-19 columb)​

Answer 1

Answer:

In the question, it is given that the charge of an electron is e=1.6×10

−19

C.

Therefore, the total charge flowing through the wire in 2 seconds will be given as 6.25×10

16

×1.6×10

−19

C=10×10

−3

C.

The rate of flow of charge is therefore

2 seconds

10×10

−3

C

=5×10

−3

C/s.

one C/s = one amp.

Hence, the current flowing through a conductor is 0.0005A, that is 5mA.
