Formulas & Step-by-Step

Resistance

R = V ÷ I

24 ÷ 794.4 = 0.0302 Ω

Power

P = V × I

24 × 794.4 = 19,065.6 W

Verification (alternative formulas)

P = I² × R

794.4² × 0.0302 = 631,071.36 × 0.0302 = 19,065.6 W ✓

P = V² ÷ R

24² ÷ 0.0302 = 576 ÷ 0.0302 = 19,065.6 W ✓

Circuit Analysis

Heat Dissipation

This circuit dissipates 19,065.6 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.

What is the power for 24V and 794.4A?expand_more

P = V × I = 24 × 794.4 = 19,065.6 watts.

What determines wire size for 794.4A?expand_more

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.
