Capacitors are sometimes connected in parallel to inductive loads to improve the power factor, raising the voltage of the source AC.
Power factor is the ratio of apparent power over true power. It is 1, if the load is purely resistive, such as in a toaster, but it is less than 1 if the load is reactive, such as in a motor. This is because current is not in phase with voltage in that case. Inductive loads cause the current to lag voltage, and capacitive loads cause the current to lead voltage. Placing capacitors across an inductive load tends to compensate for the lagging power factor.
Specifically, power factor is the cosine of the phase angle between voltage and current. In an ideal situation, with perfect sources, conductors, and reactive loads, the phase angle would be plus (capacitive) or minus (inductive) 90 degrees, and the power factor would be zero. This means that a conventional watt meter would register zero but, in reality, energy is still being supplied, and that has to be accounted for.
In practical terms, since conductors have impedance, a poor power factor degrades voltage so, adding capacitors raises voltage.

What is the differencebetween a run capacitor and start capacitor?
The run capacitor is used when the load is functional while the start capacitor is used to produce the initial torque to drive the load.
How do you connect compasstor on a Ac?
To connect a capacitor in an AC circuit, first ensure the circuit is powered off for safety. Identify the correct terminals of the capacitor, usually marked with positive (+) and negative (-) signs. Connect one terminal of the capacitor to the AC source and the other terminal to the load or ground, ensuring that the capacitor type (polarized or non-polarized) is appropriate for the application. Finally, double-check all connections before powering the circuit back on.
Is a capacitor a load?
yes
How do you connect a targa capacitor to your amplifier?
To connect a Targa capacitor to your amplifier, first ensure the amplifier is turned off and disconnected from power. Connect the positive terminal of the capacitor to the positive power terminal of the amplifier, and the negative terminal of the capacitor to the negative power terminal. Finally, connect the capacitor's ground terminal to a solid ground point on the vehicle. Always double-check your connections and polarity before powering the system back on.

What happened if the capacitor is in line when there is no load?
When there is no load on a circuit with a capacitor in the line, no current will pass. The capacitor, if charged, will remain charged until a load is put on to the circuit at which time it will discharge its designed output voltage.

When does a capacitor discharge?
A capacitor discharges when it releases the stored electrical energy it has accumulated. This typically happens when the capacitor is connected to a circuit or load that allows the energy to flow out of the capacitor.
