A current of 1ampere is drawn by a filament of an electric bulb find the number of electrons passing through a cross sections of the filament in 16sec?

Answer»

Hey mate !

I = q/ t

q = I t

q= 1 * 16

q = 16C

now ,

apply formula. .

q =ne

n = No. of ELECTRONS
e= CHARGE of electron

n = q/e

n = 16/ 1 .6 *10^-19

n = 10^20 electrons..
