What Is the Resistance and Power for 230V and 10.67A?

230 volts and 10.67 amps gives 21.56 ohms resistance and 2,454.1 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

230 ÷ 10.67 = 21.56 Ω

Power

P = V × I

230 × 10.67 = 2,454.1 W

Verification (alternative formulas)

P = I² × R

10.67² × 21.56 = 113.85 × 21.56 = 2,454.1 W

P = V² ÷ R

230² ÷ 21.56 = 52,900 ÷ 21.56 = 2,454.1 W

Circuit Analysis

Heat Dissipation

This circuit dissipates 2,454.1 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

R = V ÷ I = 230 ÷ 10.67 = 21.56 ohms.
All 2,454.1W 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.
Ohm's Law (V = IR) and the power equation (P = VI) connect all four. Given any two, you can calculate the other two.
P = V × I = 230 × 10.67 = 2,454.1 watts.
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.
