Questions
In an LCR circuit R = 100 ohm. When capacitance C is removed, the current lags behind the voltage by . When inductance L is removed, the current leads the voltage by
. The impedance of the circuit is
detailed solution
Correct option is B
When C is removed circuit becomes RL circuit hence .....(i)When L is removed circuit becomes RC circuit hence .....(ii)From equation (i) and (ii) we obtain XL = XC. This is the condition of resonance and in resonance Z = R = 100ΩTalk to our academic expert!
