In an electric furnace, the energy consumption rate (in watts) is the product of the input voltage (in volts) and the current (in amps) that flows through the

This amount of energy would be for an Industrial furnace to melt large quantities of glass or metals. Or maybe Esther has a very cold heart, and a frigid personality, and needs this for domestic heating.

Watts = Volts x Amps = 10^4 x 500 =5,000,000 = 5.0 x 10^6 Watts!!!!!!.

P.S. An "electric furnace" shouldn't use that much energy!! There appears to be something wrong with your voltage. It should be in the range of 120 to 240 volts. Check your numbers carefully.
