Formulas & Step-by-Step

Resistance

R = V ÷ I

230 ÷ 23.84 = 9.65 Ω

Power

P = V × I

230 × 23.84 = 5,483.2 W

Verification (alternative formulas)

P = I² × R

23.84² × 9.65 = 568.35 × 9.65 = 5,483.2 W ✓

P = V² ÷ R

230² ÷ 9.65 = 52,900 ÷ 9.65 = 5,483.2 W ✓

Circuit Analysis

Heat Dissipation

This circuit dissipates 5,483.2 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 230V and 23.84A?expand_more

R = V ÷ I = 230 ÷ 23.84 = 9.65 ohms.

What determines wire size for 23.84A?expand_more

Wire sizing for a given current is not an Ohm's Law calculation. It depends on run length, source voltage, voltage-drop target, conductor material, insulation and termination temperature rating, cable type, and ambient and bundling conditions. The dedicated wire-size calculator takes those variables as input.
