A $25-$km$,34\mathrm{.}5-$kV$,60-$Hz three$-$phase line has a positive$-$sequence series impedance

$.$ The load at the receiving end absorbs $10$ MVA at $33$ kV$.=0.19+0.34/$

Assuming a short line, calculate:

a$)$ The ABCD parameters

b$)$ The sending end voltage for a load power factor of $0\mathrm{.}9$ lagging

c$)$ The sending$-$end voltage for a load power factor of $0\mathrm{.}9$ leading
