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

Answer Posted / sasi karthick a

The power is depends on the resistance of the winding. Lets
Take "R"ohm resistance of winding and connect in star
configuration.

then transform it to delta. You will see the result. It
will "R/3". So low resistance, high current, power.
