Question

Solve this:
Q.6. A conductor carries a current of 0.1 A. Calculate the amount of charge that passes through the cross-section of the conductor in 1 minute. If electronic charge is 1.6$\times {10}^{-19}$ C, how many electrons will flow in this time interval?

Answer 1

Dear student,
We know that Q=It where,
Q= charge flowing in a conductor
I= current in the conductor
t=time
So, the amount of charge that passes through the cross section of conductor , Q=It
Q=$\frac{0.1}{60}=0.00167C$
If electronic charge is 1.6x10^-19C than no. of electrons flowing will be n=Q/e
n=$\frac{0.00167}{1.6\times {10}^{-19}}=1.04\times {10}^{16}$
