I assume that you are asking how to calculate the 'value' of a capacitor? Well, it depends what it is used for. If, for example, it is used to improve the power factor of a load, then it is first necessary to determine what the load's existing reactive power is; then, you need to know what reactive power is necessary with the power factor at its desired value; finally you need to difference between the actual and the desired values of reactive power -and this will be the necessary value for the capacitor. Power factor correction capacitors are rated in reactive volt amperes, not farads.

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
How do you calculate Kwh saving after installing capacitor bank?
Adding a capacitor bank makes absolutely no difference whatsoever to the amount of energy consumed (in kilowatt hours). The capacitor bank might reduce the load current, but this does not affect the amount of energy consumed. Anyone who tries to sell you a 'capacitor bank' in order to save you energy is selling a SCAM!
How do you calculate or choose capacitor bank?
Normal power is the multiplication of current to combination of resistive and reactive or capacitive load. From the vector sum of Apparent power minus real power we can get reactive power(KVAr), which is basically lagging power due to reactive load. This will be the exact rating of capacitor bank. You can find it by cos $ of apparent power.
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
What is the differencebetween a run capacitor and start capacitor?

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.
How do you calculate the powerfactor?

What are example of capacitive load?

In a capacitor circuit load angle is?
Negative.
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

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.

How do you decide KVAR rating of capacitor bank?
Generally the capacitor rating of a bank are decided on the load factor.ie higher the KVAR higher the capacity.KVAR is the reactive power in which load angle differs with the load variation.If we know load factor multiply it by the sine angle which gives us the capacity of the cpapcity of the load bank.

What are the ways to stop lagging current?
use more impedense load and use suitable capacitor bank with the load.
