Physically Large vs Small Capacitors
So, if both capacitors (small and large) have the same capacitance then one will (more than likely) work up to a larger voltage. A capacitor that is polarized (e.g. electrolytic dielectric) can be physically smaller compared to a capacitor with a better (lower loss) dielectric and this is also a significant trade-off.

What is a compensation capacitor CC?
The compensation capacitor Cc plays the main role in the frequency response of the Operational Amplifier. The return pin of Cc should be grounded, if there is such a pin and the op amp is not grounded. In this case, the capacitor current will return to one or two power supplies. (Figure 1. Block Diagram of a Non-Rail-to-Rail Amplifier)
What is a single compensation capacitor?
In single compensation, the capacitors are directly connected to the terminals of the individual power consumers and switched on together with them via a common switching device. Here, the capacitor power must be precisely adjusted to the respective consumers. Single compensation is frequently used for induction motors (Figure 4).
What types of compensation can a capacitor be used for?
Capacitors can be used for single, group, and central compensation. These types of compensation will be introduced in the following // In single compensation, the capacitors are directly connected to the terminals of the individual power consumers and switched on together with them via a common switching device.
How many capacitors are in a compensation unit?
Depending on the size of a compensation unit, it is assembled with capacitors of equal size (in bigger units) or of different size. A unit with a total reactive power of, for example, 300 kvar consists of six power capacitors, of 50 kvar each. Thus the number of capacitors is identical to the number of steps: six capacitors controlled by six steps.
What is the capacity of a capacitor?
Answer-12: The capacity of a capacitor is numerically equal to the quantity of charge which must be given to the condenser in order to maintain the unit potential difference between the plates. Question-13. On what factors the capacity of a capacitor depends?
How many capacitors are in a compensation bank?
Thus the number of capacitors is identical to the number of steps: six capacitors controlled by six steps. However, compensation banks with unequal steps, for example 50 kvar and 25 kvar (see Figure 1), enable compensation in ‘fine-stepping’ mode.
