Formulas & Step-by-Step

Resistance

R = V ÷ I

24 ÷ 340.82 = 0.0704 Ω

Power

P = V × I

24 × 340.82 = 8,179.68 W

Verification (alternative formulas)

P = I² × R

340.82² × 0.0704 = 116,158.27 × 0.0704 = 8,179.68 W ✓

P = V² ÷ R

24² ÷ 0.0704 = 576 ÷ 0.0704 = 8,179.68 W ✓

Circuit Analysis

Heat Dissipation

This circuit dissipates 8,179.68 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 340.82A?expand_more

P = V × I = 24 × 340.82 = 8,179.68 watts.

How much heat does 0.0704 ohms produce at 24V?expand_more

All 8,179.68W 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.

What determines wire size for 340.82A?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.
