The correct answer is 2160 C.
ExPlanatiOn:
- It is the given in the problem that an electric iron draws a current of 0.6 A when the voltage is 100 V.
★ Convert time from hour to second.
t = 1 h = 3600 s
★ The expression for the current in terms of charge and time as follows :
I=Q/T
Here, I is the charge, Q is the charge and t is the time.
★ Calculate the charge by rearranging. the above expression.
Q=It
Put t = 3600 s and I= 0.6 A.
Q=(0.6)(3600)
Therefore, the amount of electric charge flowing in one hour is 2160 C.
