Joule Heating Calculator

Your details

Choose which quantity to calculate. The required inputs will appear below.
Electric current through the conductor.
Electrical resistance of the conductor.
Duration of current flow.
Choose the unit for the heat energy result.
Heat energy (Q)
15,000

Total thermal energy generated by resistive heating

Energy unitJ
Power dissipated (P)250W
Voltage drop (V)50V
Power (W)250
Voltage (V)50
Heat (Q)15,000

250.00 W dissipated, generating heat energy in the conductor.

  • Power dissipated is 250.0 W - this is high-power dissipation; thermal management is critical.
  • Voltage drop across the element: 50.000 V (Ohm's law: V = IR).
  • Total heat generated: 1.500e+4 J. Increasing current has a squared effect - doubling I quadruples Q.

Next stepRemember: this calculator assumes ideal resistive behavior and, for temperature rise, adiabatic conditions. Real conductors lose heat to surroundings, so actual temperature rise is lower.
