Ohm's law

Connect voltage, current and resistance for an ohmic model.

Start with the idea

This calculator is a scientific workspace. Read the quantities and units first; use the equation only after the physical meaning is clear.

V = IR

Reference constant used by this model where applicable: 1. Keep SI units consistent before interpreting a numerical result.

Result is volts for the ohmic model.

Mendeleev

Before trusting the result, ask whether the units and order of magnitude make sense. A calculator cannot rescue a wrong physical model.
