A three-phase transmission line having a reactance of 120 ohms per phase is connected to a wye-connected load whose resistance is 160 ohms per phase. If the supply volatge is 70kV line-to-line, calculate
a) The line-to-neutral voltage per phase.
b) the line current per phase
c) the real and reactive power supplied to the load
d) the real and reacitve power absorbed by the line
e) The line-to-line voltage at the load
f) the voltage drop per phase in the line
g) The total apparent power supplied by the source

h) the total real and reactive power supplied by the source
