Answer:
Option (a) is correct.
Explanation:
Since we know that the current is the ratio of charge and time.
.......................(1)
Where i=curent flow in the circuit,q=amount of charge flow in the circuit and t is the time taken by the charge to flow from one point to other.
We have given,
i =0.2 amp, t= 1 hour=3600 sec.
We need to find the total electric charge
Using equation (1) we get,
After solving we get,
q =720 c.
So,option (a) is correct.

Answer:
It is given that an electric bulb draws a current of 0.2 ampere when the voltage is 220 volts. where, Q = Charge and t = time taken. Therefore, 720 C is the amount of electric charge flowing through it in one hour
