Question

a current of 10 ampere is passed through a lamp what charge will pass through it in 20 seconds​

Answer 1

Answer:

I = q/ t

i= 10 A

t= 20 s

q= ?

by substituting we get q =200 columbs

Answer 2

Answer:

1 ampere means 1 Columbus per second,60 seconds in a minute - so 600 Coulombs

Therefore,10 A for 1 min = 10 x 60 sec = 600 Couloumbs.

So ,10A for 20 sec=10x20 =200 Columbus
