A60-watt light bulb carries a current of 0.5 ampere. the total charge passing through it in one hour is: a) 3600 c b) 3000c c) 2400c d) 120 c e) 1800 c

Total charge, q = 1800 C

Explanation:

It is given that,

Power of light bulb, P = 60 watts

It carries a current, I = 0.5 A

Time, t = 1 hour = 3600 seconds

We need to find the total charge passing through it in one hour. We know that current through an electrical appliance is defined as the charge flowing per unit time i.e.

q = 1800 C

So, the total charge passing through it is 1800 C. Hence, this is the required solution.

v=ir = 3x15 =45 v
