Heya frnds.......... One more question of Physics. The question goes like this= How many electrons pass through a conductor in 0.2 second if current passing through it is 0.5A????? No silly answers required.

Answer»

We know I = Q/ t. since Q = ne where N is no.of ELECTRONS and e is charge of electron.
I = Q/t = ne/t
=> I = ne/t
=>0.5 A = n× 1.602 ×10 ^-19/0.2
=>0.5 = n× 8
=>n = 0.5 / 8
= > n = 0.0624 × 10^-19


hope it HELPS U
