Best ResponseYou've already chosen the best response.0Power is given by \[ P = VI \] (as units of volts is Joules/Coulomb and the units of current is Coulomb/sec) Now use the information from the problem to find current \( I \). Then the amount of charge that passes through the iron is \[ Q = It \]
