When an ac source of emf 
is connected across a circuit, the phase difference between the emf e and the current i in the circuit is observed to be 
, as shown in the diagram. If the circuit consists possibly only of RC or RL or LC in series, find the relationship between the two elements
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
A
From graph, it is clear that current leads voltage.
So possible components are R and C
For R-C circuit,
If 
, then
