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.
Is a capacitor a load?
yes

we use oil capacitor in horizontal way,This is correct or not?
How to wire a split capacitor motor?
Your two hot wires go to the load side of your contractor and the two brown wires go to your capacitor
How capacitor and resitor in a circuit effect the phase of input voltage?
A capacitor and a resistor has no effect on the supply voltage; however, this particular load combination will cause the load current to lead the supply voltage by some angle termed the 'phase angle'.
How do you UNCHARGE a capacitor?
Connect it, in series, to a resistor or a dummy load and a switch. And then throw the switch.
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.
Is a capacitor a load?
yes
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.

Why cant capacitor filter connected in series to load?
in output is pulsetting voltage remove the pulses to use the capacitor this passes the pure voltage to the load
What will happen if you connect 12volt battery to a 240VOLT capacitor?
If the capacitor is charged then the battery will explode.
What is the function of a capacitor's leads?
To connect it to the circuit.
Can blackberry 8900 connect to tv?
No, you would need an alternating capacitor to connect.
How do you use a capacitor as a power saver?
You cannot use a capacitor as a 'power saver' or, more accurately, 'energy saver'! A capacitor may improve the power-factor of a load, and this may reduce the value of its load current, but this does not reduce the energy consumed by the load. For a residence, a so-called 'power save' capacitor is nothing more than a rip-off.
