What unit is used to measure capacitive reactance?

Capacitive reactance is the opposition that a capacitor presents to the flow of alternating current (AC) due to its capacitance. The unit used to measure reactance, including capacitive reactance, is the ohm. This is because reactance is a type of impedance, which is measured in ohms, just like resistance.

To further clarify, capacitive reactance can be calculated using the formula (X_C = \frac{1}{2 \pi f C}), where (X_C) is the capacitive reactance in ohms, (f) is the frequency of the AC signal, and (C) is the capacitance in farads. While farads measure capacitance itself, and henry measures inductance, both are not used for measuring reactance. The volt, on the other hand, is a unit of electrical potential or voltage and does not relate to reactance directly. Therefore, the only appropriate unit for measuring capacitive reactance is indeed the ohm.
