Formula and methodology
Formula: V = I * R.
Voltage pushes current through resistance. Given any two quantities, the third follows from V=IR. Known values must be nonnegative; a zero divisor is rejected.
This result follows the calculator's declared inputs, precision, validation boundaries, and model limits.
Input contract
- Solve for — 3 choices
- First known value — Current in A when solving voltage; voltage in V otherwise.; minimum 0; maximum 1000000000
- Second known value — Resistance in ohms when solving voltage or current; current in A when solving resistance.; minimum 0; maximum 1000000000
Worked example
| Input | Value |
|---|---|
| Solve for | voltage |
| First known value | 2 |
| Second known value | 6 |
12 V
Assumptions and limits
- Ohmic DC behavior at constant temperature; semiconductors and AC impedance are excluded.
- All quantities are nonnegative magnitudes.
- Units: volts, amperes, ohms.
