Question

10 to the power 20 electrons each having a charge of 1.6×1019 pass form a point a towards b in0.1s.what is the current in ampere ? What is it's direction

Answer 1

the current in conductor is dq/dt=(10²°×1.6×10^-19)/0.1=16/0.1=160Aits direction is opposite the direction of electrons ie.from b to a.

Answer 2

ampere=1.6×1019/0.1=16×1019=16304A
low to high
