Formulas & Step-by-Step

Resistance

R = V ÷ I

24 ÷ 670.8 = 0.0358 Ω

Power

P = V × I

24 × 670.8 = 16,099.2 W

Verification (alternative formulas)

P = I² × R

670.8² × 0.0358 = 449,972.64 × 0.0358 = 16,099.2 W ✓

P = V² ÷ R

24² ÷ 0.0358 = 576 ÷ 0.0358 = 16,099.2 W ✓

Circuit Analysis

Heat Dissipation

This circuit dissipates 16,099.2 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

What is the resistance for 24V and 670.8A?expand_more

R = V ÷ I = 24 ÷ 670.8 = 0.0358 ohms.

How are voltage, current, resistance, and power related?expand_more

Ohm's Law (V = IR) and the power equation (P = VI) connect all four. Given any two, you can calculate the other two.

What is the power for 24V and 670.8A?expand_more

P = V × I = 24 × 670.8 = 16,099.2 watts.

Does Ohm's Law work for AC circuits?expand_more

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.

How much heat does 0.0358 ohms produce at 24V?expand_more

All 16,099.2W 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.
