Question

An electric bulb connected to a 220 V supply line draws a current of 0.05 A.

Calculate the amount of coulombs per seconds flowing through the bulb.

Answer 1

given V = 220v

I = 0.05A

t = 1s

Q = ?

we know that Q = it

or, Q = 0.05x1C

= 0.05C

so 0.05 coulombs are flowing through the bulb.
