Answer:

483000 joules

Explanation:

First find the current by the ohm's law formula. Then use the joule's law of heat, H = current^2 × resistance * time

Answer:

Explanation:

First find current

I = V/R

    230 ÷ 92

     2.5A

Then find heat

H = I²Rt

     2.5² × 92 × 14 × 60

      2.5² × 92 × 840

       6.25 × 92 × 840

       483000J
