Capacitance is the capacity of a material object or device to store electric charge. It is measured by the charge in response to a difference in electric potential, expressed as the ratio of those quantities. Commonly recognized are two closely related notions of capacitance: self capacitance and mutual capacitance. An object that can be electrically charged exhibits self capacitance, for which t…

Basic technical data of capacitors

A capacitance is the electric capacity of a capacitor, i.e. the amount of electrically charged carriers it can store. ɛ r . The relative dielectric constant can have values between ɛ r = 1 (air) and ɛ r ~ 10,000 (special ceramic materials).

Capacitance vs Capacity

Capacity is a derived term of capacitance. As nouns the difference between capacitance and capacity is that capacitance is the property of an electric circuit or its element that permits it to store charge, defined as the ratio of stored charge to potential over that element or circuit (Q/V); SI unit: farad (F) while capacity is the ability to hold, receive or absorb.

What is the capacity of capacitors in this power supply circuit?

My question is what is the capacity of these two capacitors? I mean compared to a circuit with just a single capacitor. Some people say they are in series so their capacity is halved, but I am unable to understand it. As an example: Let''s have 230 VAC, so we want to get approximately 316 VDC from AC-DC converter. We could use a single 400 V capacitor, let''s say we take 10 uF. …

A large capacitor like the 2200 uF act as a "reservoir" to store energy from the rough DC out of the bridge rectifier. The larger the capacitor the less ripple and the more constant the DC.
