Formulas & Step-by-Step

Resistance

R = V ÷ I

230 ÷ 113.23 = 2.03 Ω

Power

P = V × I

230 × 113.23 = 26,042.9 W

Verification (alternative formulas)

P = I² × R

113.23² × 2.03 = 12,821.03 × 2.03 = 26,042.9 W

P = V² ÷ R

230² ÷ 2.03 = 52,900 ÷ 2.03 = 26,042.9 W

Circuit Analysis

Heat Dissipation

This circuit dissipates 26,042.9 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 ÷ 113.23 = 2.03 ohms.
Ohm's Law (V = IR) and the power equation (P = VI) connect all four. Given any two, you can calculate the other two.
All 26,042.9W 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.
At the same 230V, current doubles to 226.46A and power quadruples to 52,085.8W. Lower resistance means more current, which means more power dissipated as heat.
P = V × I = 230 × 113.23 = 26,042.9 watts.
