The given figure represents the phasor diagram of a series LCR circuit connected to an ac source. At the instant ‘t’ when the source voltage is given by 
, then current in the circuit will be
A
B
C
( 
)
D
)
Text Solution
Verified by ExpertsThe correct answer is:
D
In an LCR circuit, the current and voltage are phase-shifted based on the reactance components (inductive and capacitive) present. The phasor diagram shows that when the source voltage is given by the expression, the current can be derived from the angle displayed in the phasor diagram. By analyzing the phase relationship between voltage and current from the given options, we conclude that Option D matches the expected phase difference between voltage and current with a cosine function.
Therefore, D.
Therefore, D.
