Which quantity is measured in ohms?

Resistance is measured in ohms. The ohm is the SI unit for electrical resistance, defined as one volt per one ampere (R = V/A). This is what Ohm’s law uses: the voltage across a component equals the current through it times its resistance. Capacitance uses farads, describing how much charge a capacitor can store; inductance uses henries, describing opposition to changes in current; and conductance uses siemens, the reciprocal of resistance. For example, if 10 volts produce 2 amperes, the resistance is 5 ohms.
