The amazing world of self induction !

The amazing world of self induction !. 130 volts / 1.4 ohms = 93 amperes! VI = 12,000 watts !. What if this coil were connected to 130 v ac???. It would melt down!!!!. The Resistance is 1.4 ohms. Ohm meter. Now follows proof that the power converted into heat is LESS
