What Is the Resistance and Power for 24V and 9.96A?

24 volts and 9.96 amps gives 2.41 ohms resistance and 239.04 watts power. Ohm's Law (V = IR) and the power equation (P = VI) connect all four electrical values. Knowing any two lets you calculate the other two instantly.

Formulas & Step-by-Step

Resistance

R = V ÷ I

24 ÷ 9.96 = 2.41 Ω

Power

P = V × I

24 × 9.96 = 239.04 W

Verification (alternative formulas)

P = I² × R

9.96² × 2.41 = 99.2 × 2.41 = 239.04 W

P = V² ÷ R

24² ÷ 2.41 = 576 ÷ 2.41 = 239.04 W

Circuit Analysis

Heat Dissipation

This circuit dissipates 239.04 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

R = V ÷ I = 24 ÷ 9.96 = 2.41 ohms.
All 239.04W 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.
V=IR, V=P/I, V=√(PR) | I=V/R, I=P/V, I=√(P/R) | R=V/I, R=V²/P, R=P/I² | P=VI, P=I²R, P=V²/R.
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.
P = V × I = 24 × 9.96 = 239.04 watts.
