Question

How many electrons are present in a current of 10 micro ampere flowing through a conductor for 1 hour

Answer 1

Answer:

22.5 ×10^16

Explanation:

According to the given question,

i = current = 10 ×10^-6 A = 10^-5 A

t = time = 1 h = 3600 sec

q = charge, n = no. of electrons

e = charge of electron

And we are asked to find the no. of electron.

We know,

• i = q/t

• q = it

• q = 10^-5 × 3600

• q = 36×10^-3

• q = 36 mC

Thus charge is 36mC.

Again,

• q = ne

• n = q/e

Putting the values we get,

• n = 36×10^-3/1.6×10^-19

• n = (36/1.6)×10^16

• n = 22.5 ×10^16

Thus no. of electron 22.5 ×10^16 for 10 micro A of current passing through the conductor for 1 h.
