Question

How.Many electron pass through a lamp.In .One minute if the cureent. Is.300ma?

Answer 1

Answer:

Explanation:Here, current I = 300 mA = 0.3 A

time t = 1 minute = 60 seconds

Now, charge Q = I x t = 0.3 x 60 = 18 coulomb

and no. of electrons = (total charge)/(charge on 1 electron)

? no. of electrons = (18)/(1.6 x 10-19)

= 1.125 x 1020 electrons
