What Is the Resistance and Power for 24V and 23.96A?

With 24 volts across a 1-ohm load, 23.96 amps flow and 575.04 watts are dissipated. These four values (voltage, current, resistance, and power) are the foundation of every electrical calculation on this site.

Formulas & Step-by-Step

Resistance

R = V ÷ I

24 ÷ 23.96 = 1 Ω

Power

P = V × I

24 × 23.96 = 575.04 W

Verification (alternative formulas)

P = I² × R

23.96² × 1 = 574.08 × 1 = 575.04 W

P = V² ÷ R

24² ÷ 1 = 576 ÷ 1 = 575.04 W

Circuit Analysis

Heat Dissipation

This circuit dissipates 575.04 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.

Same Resistance at Different Voltages

Holding the resistance constant at 1Ω, 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 ÷ 23.96 = 1 ohms.
P = V × I = 24 × 23.96 = 575.04 watts.
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.
At the same 24V, current doubles to 47.92A and power quadruples to 1,150.08W. Lower resistance means more current, which means more power dissipated as heat.
All 575.04W 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.
