Question

The relationship between line and phase voltages and currents in star connected networks is given by

Vph= VL , Iph=IL/√3

Vph=VL/√3, Iph=IL/√3

Vph= VL, Iph= IL

Vph=VL/√3, Iph= IL

Solution

Correct option is D

$\begin{array}{|c|c|c|}\hline& \textbf{Star} & \textbf{Delta} \\\hline\textbf{Voltage} & V_{Line} = \sqrt{3} \times V_{Phase} & V_{Line} = V_{Phase} \\\hline\textbf{Current} & I_{Line} = I_{Phase} & I_{Line} = \sqrt{3} \times I_{Phase} \\\hline\end{array}$
