Formulas & Step-by-Step

Resistance

R = V ÷ I

24 ÷ 339.97 = 0.0706 Ω

Power

P = V × I

24 × 339.97 = 8,159.28 W

Verification (alternative formulas)

P = I² × R

339.97² × 0.0706 = 115,579.6 × 0.0706 = 8,159.28 W

P = V² ÷ R

24² ÷ 0.0706 = 576 ÷ 0.0706 = 8,159.28 W

Circuit Analysis

Heat Dissipation

This circuit dissipates 8,159.28 watts of power as heat. In a resistor, all electrical energy at steady state converts to thermal energy. The actual component power rating needs headroom above this steady-state figure, but the specific derating depends on resistor type (carbon-comp, metal-film, wirewound each behave differently), ambient temperature, airflow or heat-sinking, and whether the load is continuous or pulsed. Check the resistor datasheet for the manufacturer-specific derating curve rather than applying a blanket margin.

Frequently Asked Questions

R = V ÷ I = 24 ÷ 339.97 = 0.0706 ohms.
V=IR, V=P/I, V=√(PR) | I=V/R, I=P/V, I=√(P/R) | R=V/I, R=V²/P, R=P/I² | P=VI, P=I²R, P=V²/R.
At the same 24V, current doubles to 679.94A and power quadruples to 16,318.56W. Lower resistance means more current, which means more power dissipated as heat.
All 8,159.28W is dissipated as heat in a pure resistor at steady state. The component power rating needs headroom above this steady-state figure, but the specific derating depends on resistor type (carbon-comp, metal-film, wirewound each behave differently), ambient temperature, airflow or heat-sinking, and whether the load is continuous or pulsed. Check the resistor datasheet for the manufacturer-specific derating curve.
