An LCR series circuit is under resonance. If Im is current amplitude, Vm is voltage amplitude, R is the resistance, Z is the impedance, XL is the inductive reactance capacitive reactance then, and Xc is the capacitive reactance then,

A)                 \[{{I}_{m}}=\frac{{{V}_{m}}}{Z}\]                             

B) \[{{I}_{m}}=\frac{{{V}_{m}}}{{{X}_{L}}}\]

C)                  \[{{I}_{m}}=\frac{{{V}_{m}}}{{{X}_{c}}}\]                             

D) \[{{I}_{m}}=\frac{{{V}_{m}}}{R}\]
