What is capacitive reactance?
Capacitive reactance is the opposition a capacitor offers to the flow of alternating current (AC). It’s measured in ohms, just like resistance. Unlike resistance, which dissipates energy as heat, capacitive reactance stores and releases energy in an electric field. Before delving into capacitor reactance, let’s grasp the fundamentals of capacitors.

There exist two primary categories of energy storage capacitors: dielectric capacitors and supercapacitors.
What determines the capacitive reactance of a capacitor?
Capacitive reactance is inversely proportional to frequency. As the frequency increases, the reactance decreases, allowing more current to flow through the capacitor.
