Question A$3$

Delta connected sources and delta connected loads of a balanced delta$-$to$-$delta three phase system

are shown in Figure $5.$ The voltage sources configured in positive sequence. One of the phase

voltage, Vab $,$ of the system is $5/\_0^($@$)$V$.$

$($a$)$ By drawing some appropriate wires in Figure $5,$ complete the connections between the

sources and loads of the balanced delta$-$to$-$delta three phase system.
