Formula

## Resistance Resistance measures how strongly a component opposes the flow of electric current. ### Formula **R = V / I** Derived from Ohm's law. The unit is the ohm (Ω), named after Georg Ohm.

Esempio Risolto

A 12 V battery drives 0.5 A through a resistor.

  1. 01R = V / I
  2. 02R = 12 / 0.5
  3. 03R = 24 Ω
