What Is the Resistance and Power for 24V and 960A?

24 volts and 960 amps gives 0.025 ohms resistance and 23,040 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 ÷ 960 = 0.025 Ω

Power

P = V × I

24 × 960 = 23,040 W

Verification (alternative formulas)

P = I² × R

960² × 0.025 = 921,600 × 0.025 = 23,040 W

P = V² ÷ R

24² ÷ 0.025 = 576 ÷ 0.025 = 23,040 W

Circuit Analysis

Heat Dissipation

This circuit dissipates 23,040 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.

Same Resistance at Different Voltages

Holding the resistance constant at 0.025Ω, here is how current and power scale with source voltage. This is a reference table, not a set of separate circuit scenarios: each row is the same resistor under a different applied voltage.

Frequently Asked Questions

R = V ÷ I = 24 ÷ 960 = 0.025 ohms.
P = V × I = 24 × 960 = 23,040 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.
At the same 24V, current doubles to 1,920A and power quadruples to 46,080W. Lower resistance means more current, which means more power dissipated as heat.
All 23,040W 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.
