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.
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.
yes
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!
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.
When the filter capacitor in a DC power supply is changed, the load voltage can be affected based on the capacitor's value. Increasing the capacitance generally results in a smoother DC output voltage with reduced ripple, leading to a more stable load voltage. Conversely, decreasing the capacitance can increase voltage ripple and cause fluctuations in the load voltage, potentially affecting the performance of connected devices. It's essential to choose the appropriate capacitor size based on the specific load requirements and ripple tolerance.

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.

The formula to calculate the maximum charge on a capacitor in an electrical circuit is Q CV, where Q represents the charge on the capacitor, C is the capacitance of the capacitor, and V is the voltage across the capacitor.

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.
To calculate the potential difference across a capacitor, you can use the formula V Q/C, where V is the potential difference, Q is the charge stored on the capacitor, and C is the capacitance of the capacitor.
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.
