Formulas & Step-by-Step

Resistance

R = V ÷ I

100 ÷ 116.66 = 0.8572 Ω

Power

P = V × I

100 × 116.66 = 11,666 W

Verification (alternative formulas)

P = I² × R

116.66² × 0.8572 = 13,609.56 × 0.8572 = 11,666 W ✓

P = V² ÷ R

100² ÷ 0.8572 = 10,000 ÷ 0.8572 = 11,666 W ✓

Circuit Analysis

Heat Dissipation

This circuit dissipates 11,666 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 100V and 116.66A?expand_more

R = V ÷ I = 100 ÷ 116.66 = 0.8572 ohms.

Does Ohm's Law work for AC circuits?expand_more

For purely resistive loads, yes. For reactive loads, use impedance (Z) instead of resistance (R). Z includes both resistance and reactance, and the V/I phase shift shows up in power factor.

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.

How much heat does 0.8572 ohms produce at 100V?expand_more

All 11,666W 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.
