What is the current flowing through a conductor if 1 million electrons are crossing in 1 millisecond through a cross section of it from A to B ? Charge on an electron `=1 .6 xx 10^(-19) C`.

Text Solution

Verified by Experts

Here, `q=10^(6) xx 1.6 xx 10^(-19) C = 1.6 xx 10^(-13)C, t = 10^(-3)s`
Now, current `I = q/t = (1.6 xx 10^(-13))/10^(-3) = 1.6 xx 10^(-10)A`
The direction of current in conductor is from B to A.
