$)$ A balanced wye$-$connected load with $=$ per phase is supplied by a balanced three$-$phase wye$-$connected source $(120$ V line$-$to$-$neutral, $=60$ Hz$).$ Use $$ as the reference voltage, i$.$e$.,=$ V$.$ a$)$ Compute the currents across the load, $,,$ and $$ and the supply power factor. b$)$ Compute the transmission line currents, $,,$ and $.$ c$)$ If a delta$-$connected capacitor bank with impedance $$ per phase is connected in parallel with the load, recompute the supply power factor and the transmission line currents.
