What Is the Resistance and Power for 24V and 152A?

With 24 volts across a 0.1579-ohm load, 152 amps flow and 3,648 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 ÷ 152 = 0.1579 Ω

Power

P = V × I

24 × 152 = 3,648 W

Verification (alternative formulas)

P = I² × R

152² × 0.1579 = 23,104 × 0.1579 = 3,648 W

P = V² ÷ R

24² ÷ 0.1579 = 576 ÷ 0.1579 = 3,648 W

Circuit Analysis

Heat Dissipation

This circuit dissipates 3,648 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 0.1579Ω, 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 ÷ 152 = 0.1579 ohms.
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.
Ohm's Law (V = IR) and the power equation (P = VI) connect all four. Given any two, you can calculate the other two.
All 3,648W 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.
