A balanced three-phase voltage is applied to a star-connected induction motor, the phase to neutral voltage being V. The stator resistance, rotor resistance referred to the stator, stator leakage reactance, rotor leakage reactance referred to the stator, and the magnetizing reactance are denoted by $$r_s,\;r_r,\;r_s,\;r_r\;and\;X_m$$, respectively. The magnitude of the starting current of the motor is given by
A
$$\frac V{\sqrt{\left(r_s+r_r\right)^2+\left(x_s+x_r\right)^2}}$$
B
$$\frac V{\sqrt{r_s^2+\left(r_s+X_m\right)^2}}$$
C
$$\frac V{\sqrt{\left(r_s+r_r\right)^2+\left(X_m+x_r\right)^2}}$$
D
$$\frac V{\sqrt{r_s^2+\left(X_m+x_r\right)^2}}$$
