Question

If charge passes through a wire is 0.5c then current of 50 ma will flow in

Answer 1

Using I = q/t where q is charge, t is time and I is current. q = I × t , q = n × e. Where n is number of electron and e is charge on electron.

Solving for n, n = (I× t)/e = (0.2 × 0.5)/ 1.6 × 10^-19

= 0.0625 × 10^19 = 6.25 × 10^17 electron will pass in 0.2 sec.

Hope this will help
