detailed solution

Correct option is C

The current of 1.6 A lags emf in phase by π/2. The current of 0.4 A leads emf in phase byπ/2. So, these two currents are 1800 out of phase with each other. ∴Net current, I1=1.6-0.4A=1.2A1.6=EVXL and 0.4 = EVXC⇒XCXL=4⇒1ωCωL=4⇒ω=12LC

An LCR circuit contains resistance of 100Ω and a supply of 200 V at 300 rad angular frequency. If only capacitance is taken out from the circuit and the rest of the circuit is joined, current lags behind the voltage by 600. If, on the other hand, only inductor is taken out, the current leads by 600 with the applied voltage. The current flowing in the circuit is
