1.	In an ac circuit shown in fig , the supply voltage has a constant rms value v but variable frequency f. At resonance, the circuit A. has a current `I` given by `I=V/R`B. has a resonance frequency `500 Hz`C. has a voltage across the capacitor which is `180^(@)` out of phase with that across the inductorD. has a current given by =`V/sqrt(R^(2)+(1/pi+1/pi)^(2))`
Answer» Correct Answer - A,B,C Resonance frequency `f=1/(2pi)1/sqrt(LC)=500 Hz` At resonance `Z=R` &`I=V/z=V/R` `L` & `C` are in out of phase.
