Fundamental Physics/Electronics/Resistance

The resistance of an object describes how much it inhibits the flow of electrical current. It is measured in the unit ohms. An object with a resistance of 1 ohm will allow 1 amp to pass through it at 1 volt. The relationship is linear, thus 10V across 2 ohms allows 5 amps to flow.

Reistance Formula

R={\frac {V}{I}}
