Question

An electric bulb draw a electric current 0.2A when voltage was 220 volt. Find the amount of electric charge flow in 1 hour

Answer 1

we have the formula

I = q/t

where
I is the current
q is the amount of electric charge
t is the time

or

amount of electric charge

q = I.t

here

I = current = 0.2 A

t = time = 1hr = 3600 s

so,

q = 0.2 x 3600

thus,

q = 720 C
