An electrical drive draws 2 kw power from AC mains [ Voltage $223 V(rms) = \sqrt {50,000}\;v$ ]. The current differs (lags) in phase by $\phi (\tan \phi = -\large\frac{-3}{4} )$ as compared to voltage . Find $I_{max}$ another device has twice the value of $R,X_c$ and $X_L$. How are the answers affected ?

Question

$\begin{array}{1 1} I_{max} = 1.26\;A \\ I_{max} = 0.126\;A \\ I_{max} = 12.6\;A \\ I_{max} = 126\;A \end{array}$
