What Is the Resistance and Power for 24V and 10.54A?

24 volts and 10.54 amps gives 2.28 ohms resistance and 252.96 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 ÷ 10.54 = 2.28 Ω

Power

P = V × I

24 × 10.54 = 252.96 W

Verification (alternative formulas)

P = I² × R

10.54² × 2.28 = 111.09 × 2.28 = 252.96 W

P = V² ÷ R

24² ÷ 2.28 = 576 ÷ 2.28 = 252.96 W

Circuit Analysis

Heat Dissipation

This circuit dissipates 252.96 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.

P = V × I = 24 × 10.54 = 252.96 watts.
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.
Ohm's Law (V = IR) and the power equation (P = VI) connect all four. Given any two, you can calculate the other two.
All 252.96W 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.
