What quantity is measured in Ohms?

Explanation:
Ohms describe how much a component resists the flow of electric current. In practice, resistance is what limits how much current can pass for a given voltage, and it’s defined by Ohm’s law as R = V / I. The unit of resistance is the ohm (Ω), which equals a volt per ampere. That’s why the quantity expressed in ohms is resistance. To contrast the other quantities: current is measured in amperes (A), voltage in volts (V), and power in watts (W). An ohm measures how strongly a component resists current, not how much current flows or how much voltage is present. A handy everyday takeaway: when you measure resistance with an ohmmeter, you’re reading this Ω value that tells you how much the component resists current.
