The current I in an A.C. circuit with inductance coil varies with time according to the graph given below
Which one of the following graphs gives the variation of voltage with time.
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
A
In an A.C. circuit with inductance coil, the voltage 
leads the current 
by a phase difference of 
. Or the current 
lags behind the voltage 
by a phase difference of 
. Thus the voltage goes on decreasing with the increase in time as shown in the graph.
