Which expression gives the current amplitude in a series LCR circuit?
पर्याय
\[i_m=v_mZ\]
\[i_m=\frac{v_m}{X_C+X_L}\]
\[i_m=\frac{v_m}{Z}\]
\[i_m=\frac{Z}{v_m}\]

उत्तर
Current amplitude is the voltage amplitude divided by impedance. Thus, for a given voltage amplitude, a smaller impedance produces a larger current amplitude.
