# Electric Resistance

Resistance \((R)\) is the ability to resist or prevent the flow of current. In order to overcome the resistance and get the current to flow a higher voltage will be required. Resistance is measured in Ohms, represented by \(R\) and has a symbols \(\Omega\).

Ohm is a unit of resistance. A constant current of one ampere produces a force of one volt.
