Formulas & Step-by-Step

Resistance

R = V ÷ I

24 ÷ 343.33 = 0.0699 Ω

Power

P = V × I

24 × 343.33 = 8,239.92 W

Verification (alternative formulas)

P = I² × R

343.33² × 0.0699 = 117,875.49 × 0.0699 = 8,239.92 W

P = V² ÷ R

24² ÷ 0.0699 = 576 ÷ 0.0699 = 8,239.92 W

Circuit Analysis

Heat Dissipation

This circuit dissipates 8,239.92 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.

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.
At the same 24V, current doubles to 686.66A and power quadruples to 16,479.84W. Lower resistance means more current, which means more power dissipated as heat.
P = V × I = 24 × 343.33 = 8,239.92 watts.
