Question

An electronic bulb draws a current of 0.25 A for 20 minutes . calculate the amount of electric charge. that flows throught the circuit.

Answer 1

current = I = 0.25A
time = t = 20 min = 20×60 = 1200 s
amount of charge = Q = ?

I = Q/t
Q = It
Q = 0.25A×1200s
Q = 300As
Q = 300 coulombs

Answer 2

I=.25A
t=20min=20×60sec
Q=?
we know,
I=Q/t
Q=I×t
Q=.25×20×60
Q=300 Couloumb
amount of electric charge that flows through the circuit is 300 Couloumb
