Formulas & Step-by-Step

Resistance

R = V ÷ I

120 ÷ 59.99 = 2 Ω

Power

P = V × I

120 × 59.99 = 7,198.8 W

Verification (alternative formulas)

P = I² × R

59.99² × 2 = 3,598.8 × 2 = 7,198.8 W ✓

P = V² ÷ R

120² ÷ 2 = 14,400 ÷ 2 = 7,198.8 W ✓

Circuit Analysis

Heat Dissipation

This circuit dissipates 7,198.8 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 120V and 59.99A?expand_more

R = V ÷ I = 120 ÷ 59.99 = 2 ohms.

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.

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 much heat does 2 ohms produce at 120V?expand_more

All 7,198.8W 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.
