Formulas & Step-by-Step

Resistance

R = V ÷ I

24 ÷ 426.38 = 0.0563 Ω

Power

P = V × I

24 × 426.38 = 10,233.12 W

Verification (alternative formulas)

P = I² × R

426.38² × 0.0563 = 181,799.9 × 0.0563 = 10,233.12 W

P = V² ÷ R

24² ÷ 0.0563 = 576 ÷ 0.0563 = 10,233.12 W

Circuit Analysis

Heat Dissipation

This circuit dissipates 10,233.12 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 ÷ 426.38 = 0.0563 ohms.
All 10,233.12W 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.
P = V × I = 24 × 426.38 = 10,233.12 watts.
At the same 24V, current doubles to 852.76A and power quadruples to 20,466.24W. Lower resistance means more current, which means more power dissipated as heat.
Ohm's Law (V = IR) and the power equation (P = VI) connect all four. Given any two, you can calculate the other two.
