Formulas & Step-by-Step

Resistance

R = V ÷ I

24 ÷ 965.78 = 0.0249 Ω

Power

P = V × I

24 × 965.78 = 23,178.72 W

Verification (alternative formulas)

P = I² × R

965.78² × 0.0249 = 932,731.01 × 0.0249 = 23,178.72 W

P = V² ÷ R

24² ÷ 0.0249 = 576 ÷ 0.0249 = 23,178.72 W

Circuit Analysis

Heat Dissipation

This circuit dissipates 23,178.72 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 ÷ 965.78 = 0.0249 ohms.
Ohm's Law (V = IR) and the power equation (P = VI) connect all four. Given any two, you can calculate the other two.
P = V × I = 24 × 965.78 = 23,178.72 watts.
All 23,178.72W 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.
Wire sizing for a given current is not an Ohm's Law calculation. It depends on run length, source voltage, voltage-drop target, conductor material, insulation and termination temperature rating, cable type, and ambient and bundling conditions. The dedicated wire-size calculator takes those variables as input.
