In an LCR circuit 
. 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
Text Solution
Verified by ExpertsThe correct answer is:
B
When 
is removed, circuit becomes 
circuit.
Hence, 
(i)
When 
is removed, circuit becomes 
circuit.
Hence, 
..(ii)
From Eqs. (i) and (ii),
we obtain 
;
this is the condition of resonance
