In an AC - circuit , the current lags behind the voltage by ` pi `/ 3 . The components in the circuit may be

A

1A

B

1.5A

C

2A

D

2.5A

Text Solution

Verified by Experts

The correct Answer is:
C
According to the given question
`tan 60^(@) =(omega L)/(R ) and tan 60^(@) =(1//omega C)/(R )`
`:. (omega L)=(1//omega C)( "case of resonance")`
Now ` Z=sqrt(R^(2)+(omega L-(1)/(omega C))^(2))=100 Omega`
`:. I_(rms)=(E_(rms))/(Z) =(200 V)/(100 Omega)=2A`.
