Formulas & Step-by-Step

Resistance

R = V ÷ I

230 ÷ 22.97 = 10.01 Ω

Power

P = V × I

230 × 22.97 = 5,283.1 W

Verification (alternative formulas)

P = I² × R

22.97² × 10.01 = 527.62 × 10.01 = 5,283.1 W ✓

P = V² ÷ R

230² ÷ 10.01 = 52,900 ÷ 10.01 = 5,283.1 W ✓

Circuit Analysis

Heat Dissipation

This circuit dissipates 5,283.1 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.

If You Change the Resistance

Frequently Asked Questions

What is the resistance for 230V and 22.97A?expand_more

R = V ÷ I = 230 ÷ 22.97 = 10.01 ohms.

What happens if I halve the resistance?expand_more

At the same 230V, current doubles to 45.94A and power quadruples to 10,566.2W. Lower resistance means more current, which means more power dissipated as heat.

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 are all 12 Ohm's Law formulas?expand_more

V=IR, V=P/I, V=√(PR) | I=V/R, I=P/V, I=√(P/R) | R=V/I, R=V²/P, R=P/I² | P=VI, P=I²R, P=V²/R.

How much heat does 10.01 ohms produce at 230V?expand_more

All 5,283.1W 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.
