Question

How many electrons will contribute in one second in causing one micro ampere of current? prove it​

Answer 1

Answer:

Explanation:

If you are asking how many electrons will pass a given point in one second with a current of 1 microampere, then the answer is easy. An ampere is one Coulomb per second, or A = C/s. A Coulomb = 6.241509×10^18 electrons so you get 6.241509×10^12 electrons passing a given point in one second (one microCoulomb).
