WebA capacitor is an electromechanical two-terminal component that stores potential energy. It has a dielectric material such as air or oil which resists changes in electrical potential between its two conductors. Ideal resistors have zero reactance, meaning they don’t store or dissipate electrical charge. WebFeb 13, 2024 · We can calculate the capacitive reactance X of a capacitor C using the following equation: X = 1 / (2 × π × f × C). Alternatively, we can write the capacitive reactance formula as: X = 1 / (ω × C), where ω = 2 × π × f is the angular frequency of the current. 🙋 You can always find the capacitance by checking the capacitor code and ...
