In the figure, which of the phasor diagrams represents `RLC` circuit driven at resonance?

A

B

C

D

Text Solution

Verified by Experts

The correct Answer is:
C
At resonance, `V_(L) = V_(C )` also `V_(L)` and `V_(C )` are in opposite phase. A series `LCR` circuit containing a resistance of 120 has an angular resonance frequency. At resonance, voltage across resistance and inductance are `60 V` and `40 V`
