AI Customer ServiceSo we say that current leads voltage in a capacitive load. An inductive load is one which upon initial turn-on presents an open circuit, and the voltage is high before the current begins to flow. So we say that current lags behind voltage in an inductive load.
Capacitive loads store electrical energy in a capacitor and release it back into the circuit. Unlike resistive loads or inductive loads, CLs have the characteristic of the current reaching its peak before the voltage does.
The only difference is that, in capacitive load current leads the voltage by 90 deg. Whereas, in inductive load current lags behind the voltage by 90 deg. Now, let’s talk about the misconception on which I spoke in the beginning of this video.
The voltage at which the capacitors are applied can vary +5% or even up to +10%. Voltage less than nominal is not a concern for as the lower voltage will result in lower capacitor current. Harmonics can create additional current flow in the capacitors any where from +20% to +35% of the rated current.
Every capacitive load has some internal resistance. In capacitive load, Current leads voltage by 90 degrees. Hence it has a leading power factor. Since the capacitor blocks DC current and allows AC to pass through it, the capacitive load shows very high resistance for DC supply and low resistance for AC.
Start by imagining a capacitor connected to a voltage source. The voltage of the voltage source doesn't change no matter what load you present to it, including that load being a capacitor. The only question is what the current will be. The current thru a capacitor is always the derivative of the voltage across it. That's what capacitors do.
