Formulas & Step-by-Step

Resistance

R = V ÷ I

24 ÷ 973.5 = 0.0247 Ω

Power

P = V × I

24 × 973.5 = 23,364 W

Verification (alternative formulas)

P = I² × R

973.5² × 0.0247 = 947,702.25 × 0.0247 = 23,364 W ✓

P = V² ÷ R

24² ÷ 0.0247 = 576 ÷ 0.0247 = 23,364 W ✓

Circuit Analysis

Heat Dissipation

This circuit dissipates 23,364 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

What is the resistance for 24V and 973.5A?expand_more

R = V ÷ I = 24 ÷ 973.5 = 0.0247 ohms.

How much heat does 0.0247 ohms produce at 24V?expand_more

All 23,364W 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.

How are voltage, current, resistance, and power related?expand_more

Ohm's Law (V = IR) and the power equation (P = VI) connect all four. Given any two, you can calculate the other two.

What determines wire size for 973.5A?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.
