Formula and methodology
Formula: For an ideal ohmic resistor, current I = V ÷ R. Supporting relationships are power P = VI and conductance G = 1/R.
The voltage sign is preserved so current direction follows the chosen reference direction. The model is for a resistance that behaves ohmically; it is not a general diode, motor, battery, or nonlinear device simulator.
This result follows the calculator's declared inputs, precision, validation boundaries, and model limits.
Input contract
- Voltage across the resistance — V; minimum -1000000000; maximum 1000000000
- Resistance — Ω; minimum 1.0E-6; maximum 1000000000
Worked example
| Input | Value |
|---|---|
| Voltage across the resistance | 12 |
| Resistance | 100 |
Current = 12 ÷ 100 = 0.12 A; power = 1.44 W.
Assumptions and limits
- Voltage is the potential difference across the same resistance and is entered in volts.
- Resistance is positive and entered in ohms.
- The device is treated as ohmic over the stated operating point.
- Current sign follows the voltage reference direction chosen by the visitor.
- Power is the signed algebraic product VI; its interpretation depends on the chosen passive sign convention.
- Temperature-dependent resistance, tolerance, parasitics, and frequency effects are not modeled.
- The page does not calculate a complete circuit with series, parallel, source, or load interactions.
- Nonlinear components such as diodes are outside the simple Ohm-law model.
- Do not use the result as a wire ampacity, breaker selection, or electrical-safety approval.
