Formulas & Step-by-Step

Resistance

R = V ÷ I

460 ÷ 10.77 = 42.71 Ω

Power

P = V × I

460 × 10.77 = 4,954.2 W

Verification (alternative formulas)

P = I² × R

10.77² × 42.71 = 115.99 × 42.71 = 4,954.2 W ✓

P = V² ÷ R

460² ÷ 42.71 = 211,600 ÷ 42.71 = 4,954.2 W ✓

Circuit Analysis

Heat Dissipation

This circuit dissipates 4,954.2 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 460V and 10.77A?expand_more

R = V ÷ I = 460 ÷ 10.77 = 42.71 ohms.

How much heat does 42.71 ohms produce at 460V?expand_more

All 4,954.2W 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.

What determines wire size for 10.77A?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.
