Ohm's law

Equation and meaning

\[V = IR\]

Ohm's law Where : V is the Voltage,I is the Current,R is the Resistance,

Variables in this formula

IR — Ir
Enter this value unless it is the selected unknown.
V — Voltage
Voltage SI unit: V

How to use this calculator

  1. Leave one value emptyThe empty field is automatically treated as the unknown.
  2. Enter known values and unitsChoose N, kgf, dyn, SI or another compatible unit when available.
  3. Review the automatic answerThe result appears immediately and is substituted back into the formula to check the residual.
