A $60-$KVA, $220$ V$,50-$Hz$,1$ phase alternator has effective armature resistance of$0\mathrm{.}016$ ohm and an armature leakage reactance of $0\mathrm{.}07$ ohm. Compute the voltage induced in thearmature when the alternator is delivering rated current at a load power factor of $($a$)$ unity $($b$)0\mathrm{.}7$lagging and $($c$)0\mathrm{.}7$ leading. $(225,234,208$V$)$
