Can anyone help me on this pl?

a. Convert a star connected load of 30 ohms per phase to it's equivalent Delta?

b. Convert a Delta connected load of 45 ohms per phase to its equivalent star?

immediate help would be much appreciated.

 

If you google "delta wye", this comes up. It's all you need.
