A circuit having a pure capacitor of capacitance C farads is known as a pure capacitor circuit. The effect of storing electrical power in the electric field is known as capacitor capacitance. The condenser is another name for it. The capacitor is made up of two conducting plates separated by a dielectric substance.
Voltage lags current by 90 degrees in a purely capacitive circuit, that is, a circuit comprising just a pure capacitor with capacitance C. As a result, there is a 90° phase shift between voltage and current.
Although theoretically feasible, a pure capacitive load has zero resistance, as every capacitive load has some internal resistance. 3. A capacitive load's current always lags after the voltage applied across the load.
