What is the resistance of the wire

Reference no: EM13316094

Older freezers developed a coating of ice inside that had to be melted periodically; an electric heater could speed this defrosting process. Suppose you're melting ice from your freezer using a heating wire that carries a current of 3.0A when connected to 120 V.

part A - What is the resistance of the wire?

part B - How long will it take the heater to melt 810g of accumulated ice at -10 %u2218C? Assume that all of the heat goes into warming and melting the ice, and that the melt water runs out and doesn't warm further.
