What Is the Resistance and Power for 100V and 5.94A?

100 volts and 5.94 amps gives 16.84 ohms resistance and 594 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

100 ÷ 5.94 = 16.84 Ω

Power

P = V × I

100 × 5.94 = 594 W

Verification (alternative formulas)

P = I² × R

5.94² × 16.84 = 35.28 × 16.84 = 594 W

P = V² ÷ R

100² ÷ 16.84 = 10,000 ÷ 16.84 = 594 W

Circuit Analysis

Heat Dissipation

This circuit dissipates 594 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 = 100 ÷ 5.94 = 16.84 ohms.
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.
All 594W 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.
