Current Electricity

Question

A 60 watt bulb carries a current of 0.5 ampere. Find the total charge passing through it in 1 hour.

Answer

Current carried by the bulb, I= 0.5 A
Time given, t = 1 hour= 3600 sec
Therefore,
Charge passing through the bulb, q = It
                                                  = 0.5 x (60 x 60)
                                                  = 1800 C
