The value of current in two series `LCR` circuits at resonance is same when connected across a sinusodial voltage source. Then:

Options

A. Both circuits must be having same value of capacitance and inductor
B. In both circuits ratio of L and C will be same
C. For both the circuits `X_(L)//X_(C)` must be same at that frequency
D. Both circuits must have same impedance at all frequencies .

Answer

C
