What is the resistance of a 1200 W electric frying pan that draws a current of 11a?

One of the handy formulas for the power dissipated by a circuit element is       Power = (current)² x (resistance) .That certainly seems to be the one to use for this problem, since we're given the power and the current, and we're asked to find the resistance.              Power = (current)² x (resistance) .Divide each side by (current)² :                 Resistance = (power) / (current)²             Resistance = (1200W) / (11 A)²             Resistance = 1200 / 121  =  9.917... ohms  (rounded)
