A load of $10$ at $0\mathrm{.}8$ power factor lagging is connected across the low$-$voltage terminals of

the transformer. The voltage measured across the load side is $110$ V$.$ Compute the following:

a$.$ Load voltage referred to the primary side

b$.$ Currents of the primary and secondary winding

c$.$ Source voltage

d$.$ Voltage regulation

e$.$ Load power
