Question

Why we use polarized capacitor?

Answer 1

Polarized Capacitor:

1. These are a certain types of capacitors that have specific positive and negative polarities.
2. These polarized capacitors have to be connected according to their polarities in circuits.
3. While using these capacitors in circuits, it should always be taken care that they are connected in perfect polarities.
4. The figure shows an example of electrolytic capacitor

Uses

1. These capacitors are used in various filtering devices to lower the fluctuations.
2. These are used for energy in various devices, polarized capacitors are better than normal capacitors in storing energy.
3. These are used in noise filtering in many electronic devices also.
