What is the power ratio between power in Star and Delta
circuit?

Answer Posted / ganesh

Power ratio between star and delta is 1:1
because power in star=line voltage(3^1/2*Vph)*line current
(Iph)=3^1/2VphIph
power in delta =line voltage(Vph)*line current(3^1/2*Iph)
=3^1/2VphIph

Is This Answer Correct ?    22 Yes 17 No
