Question

A conductor has 6.25 x 10^18 free electrons. What is the net charge on the conductor if each electron has a charge ((e=1.6×10^−19 C)

Answer 1

Answer:

Coulomb. The SI unit of electrical charge. One coulomb (symbol C) is equal in magnitude to the total charge of 6.25 x 10^18 electrons.

Answer 2

Answer:

In the question, it is given that the charge of an electron is e = 1.6 x10 19 С.

Therefore, the total charge flowing through the wire in 2 seconds will be given as 6.25 x 1016 x 1.6 x 10-19 С = 10 x 103 C.

The rate of flow of charge is therefore 10 x 10-3 -3 C 2 seconds = 5 x 10-3 C/s.

one C/s = one amp.

Hence, the current flowing through a conductor is 0.0005A, that is 5mA.
