Question

1)An electric heater operating at full power draws a current of 13.1 A from a 123 V circuit. What is the resistance of the heater? Answer in unitsof .
2)Assuming constant R, how much current should the heater draw in order to dissipate 1130 W? Answer in units of A.
for part 1 i got 9.4 by dividing 123 V by 13.1 A for part two would I would set up the equationI=(.5*1130W*9.4)^1/2 is this correct? 1)An electric heater operating at full power draws a current of 13.1 A from a 123 V circuit. What is the resistance of the heater? Answer in unitsof .

Explanation / Answer

1) R = V/I = 123V/13.1A = 9.4 2) since R is constant, we have: P = IV = I2 R ->I = (P/R) = (1130W/9.4) =10.96A .
