A $10$ KVA, $480/240-$V$,60$ Hz$,$ singlephase conventional transformer is supplying $8\mathrm{.}5$ KW power to a load at

$0\mathrm{.}85$ Lagging power factor, and a load voltage of $240$ Volts.

The Equivalent circuit $($referred to secondary$)$ is given below.

Calculate the following magnitudes and angles in degrees :

The load current is: $\backslash ($ I$\_\{$S$\}=\backslash )$

Amperes.

The input voltage referred to secondary

$\backslash (\backslash$mathbf$\{$v$\}\_\{\backslash$mathrm$\{$p$\}\}/\backslash$mathbf$\{$a$\}=\backslash )\backslash (\{\}^\{\backslash$circ$\}\backslash )$ Volts.

The input voltage is $\backslash (\backslash$mathbf$\{$V$\}\_\{\backslash$mathbf$\{$p$\}\}=\backslash )$

$\backslash (\{\}^\{\backslash$circ$\}\backslash )$ Volts.

The Voltage Regulation is $\backslash \%$VR $=\backslash \%.$
