What is the unit for measuring resistance?

Explanation:
Resistance is measured in ohms. This follows Ohm's law, V = IR. If you solve for R, you get R = V/I, so the unit that naturally fits is volt per ampere, defined as one ohm. The ohm is symbolized by the Greek omega. Volts measure electrical potential, amps measure current, and watts measure power, so the unit for resistance stands apart as the ohm. For example, if 2 volts are across a component drawing 0.5 amps, the resistance is 4 ohms.
