Formulas & Step-by-Step

Resistance

R = V ÷ I

100 ÷ 113.15 = 0.8838 Ω

Power

P = V × I

100 × 113.15 = 11,315 W

Verification (alternative formulas)

P = I² × R

113.15² × 0.8838 = 12,802.92 × 0.8838 = 11,315 W ✓

P = V² ÷ R

100² ÷ 0.8838 = 10,000 ÷ 0.8838 = 11,315 W ✓

Circuit Analysis

Heat Dissipation

This circuit dissipates 11,315 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 113.15A?expand_more

R = V ÷ I = 100 ÷ 113.15 = 0.8838 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.

What is the power for 100V and 113.15A?expand_more

P = V × I = 100 × 113.15 = 11,315 watts.

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.

What happens if I halve the resistance?expand_more

At the same 100V, current doubles to 226.3A and power quadruples to 22,630W. Lower resistance means more current, which means more power dissipated as heat.
