i need solution to that question.What's your problem?
What have YOU done to try to answer YOUR homework problem?I have a problem solving the following assignment question.
A star-connected balanced three phase load 30 ohms resistance per phase is supplied by 415 v, three-phase generator of efficiency 90%. calculate the power input to the generator.
Why are you dividing the voltage by sqrt(3) twice?Vph=415/√3=239.6
V=IR
Iph=v/R = 239.6/30=7.99
VL =√3Vph
Vph=239.6/√3=138.3
IL=138.3/30=4.6A
p=3*I2R
=3*4.62*30=1917w
this is what i got please assist me
