Formulas & Step-by-Step

Resistance

R = V ÷ I

24 ÷ 996 = 0.0241 Ω

Power

P = V × I

24 × 996 = 23,904 W

Verification (alternative formulas)

P = I² × R

996² × 0.0241 = 992,016 × 0.0241 = 23,904 W ✓

P = V² ÷ R

24² ÷ 0.0241 = 576 ÷ 0.0241 = 23,904 W ✓

Circuit Analysis

Heat Dissipation

This circuit dissipates 23,904 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 996A?expand_more

R = V ÷ I = 24 ÷ 996 = 0.0241 ohms.

What determines wire size for 996A?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.

Does Ohm's Law work for AC circuits?expand_more

For purely resistive loads, yes. For reactive loads, use impedance (Z) instead of resistance (R). Z includes both resistance and reactance, and the V/I phase shift shows up in power factor.

How much heat does 0.0241 ohms produce at 24V?expand_more

All 23,904W 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.
