if i have a coli of 242kW on a 110V Dc system...how much current is require to energize the coil?...i think a current of 2.2A would energize the cirucit....
If you're asking how much current you need for 242kW at 110V DC then the answer is 2200A. If you're asking something different then I'm not sure what you're asking.

If we learn from our mistakes I'm getting a great education!
I have done a rather thorough research on the subject and I did come up with an alternate answer that I believe can be of some interest. If we assume that m means "milli", M means "mega" and A means "ampere", then the following expression also holds:
I [mA] = P [kW] / U [MV]
Please note that this is a preliminary result. It may need to be checked in a model circuit.
