PHXII07:ALTERNATING CURRENT

356244 Statement A :
Resonance is exhibited by a circuit only if both L and C are present in the circuit.
Statement B :
In resonance the voltage across L and C cancel each other, both being out of phase.

1 Statement A is correct but Statement B is incorrect.
2 Statement A is incorrect but Statement B is correct.
3 Both Statements are correct.
4 Both Statements are incorrect.
PHXII07:ALTERNATING CURRENT

356245 In an \(LCR\) \(a.c\) circuit at resonance, the current

1 Is always in phase with the voltage
2 Always leads the voltage
3 Always lags behind the voltage
4 May lead or lag behind the voltage
PHXII07:ALTERNATING CURRENT

356246 At resonance the peak value of current in \(L-C-R\) series circuit is

1 \(E_{0} / Z\)
2 \(\dfrac{E_{0}}{\sqrt{R^{2}+\left(\omega L-\dfrac{1}{\omega C}\right)^{2}}}\)
3 \(\sqrt{2} \sqrt{R^{2}+\left(\omega^{2} L-\dfrac{1}{\omega^{2} C^{2}}\right)^{2}}\)
4 \(\dfrac{E_{0}}{\sqrt{2} R}\)
PHXII07:ALTERNATING CURRENT

356247 Read the Statement - A and Statement - B carefully to mark the correct options given below:
Statement A :
An AC circuit undergoes electrical resonance if it contains either a capacitor or an inductor.
Statement B :
An AC circuit containing a pure capacitor or a pure inductor consumes high power due to its non-zero power factor.

1 Both Statement A and Statement B are incorrect.
2 Statement A is correct but Statement B is incorrect.
3 Statement A is incorrect but Statement B is correct.
4 Both Statement A and Statement B are correct.
