Explanation:
Given A current of 5 mA is flowing in a wire. cross-section of wire
How many electrons pass through per minute?
- So a current of 5 mA is flowing through a wire.
- We need to find the number of electrons which passes through any cross section of the wire per minute.
- So current I = 5 mA = 5 x 10^-3 A
- Time t = 1 min = 60 secs
- Now we have I = n x e/t where I is the current and n is the number of electrons passing and t is the time.
- So I = n x e/t
- 5 x 10^-3 = n x 60 / 1.6 x 10^-19
- 5 x 10^-3 / n = 1.6 x 10^-19 / 60
- Or n = 5 x 60 x 10^-3 / 1.6 x 10^-19
- n = 300 x 10^-3 / 1.6 x 10^-19
- n = 187.5 x 10^16
