#### Explain Capacitance, Inductance, Resistance. - Electronics

a) Capacitance b) Inductance c) Resistance a) Capacitance: The amount of charge that can be stored inside a capacitor at a given voltage is called Capacitance. It gets charged when charges are forced into the positive (or upper) plate of the capacitor due to emf. Similarly, it discharged when charges are forcefully pulled out of the capacitor.

#### Capacitive Reactance - The Reactance of Capacitors

where: ƒ = frequency in Hertz and C = capacitance in Farads Therefore, it can be seen from above that as the frequency applied across the 220nF capacitor increases, from 1kHz to 20kHz, its reactance value, X C decreases, from approx 723Ω to just 36Ω and this is always true as capacitive reactance, X C is inversely proportional to frequency with the current passed by the capacitor for a

Capacitance definition is - the property of an electric nonconductor that permits the storage of energy as a result of the separation of charge that occurs when opposite surfaces of the nonconductor are maintained at a difference of potential.

#### Capacitor and Capacitance - Formula, Uses, Factors

A variable capacitor is a capacitor whose capacitance can be varied to a certain range of values based on the necessity. The two plates of the variable capacitor are made of metals where one of the plates is fixed and the other plate is movable. Their main function is to fix the resonant frequency in the LC circuit.

#### How Capacitors Work | HowStuffWorks

10/2/2021· A capacitor is much simpler than a battery, as it can''t produce new electrons -- it only stores them. In this article, we''ll learn exactly what a capacitor is, what it does and how it''s used in electronics. We''ll also look at the history of the capacitor and how several people helped shape its progress.

#### Factors Affecting Capacitance | Capacitors | Electronics

There are three basic factors of capacitor construction determining the amount of capacitance created. These factors all dictate capacitance by affecting how much electric field flux (relative difference of electrons between plates) will develop for a given amount of electric field force (voltage between the two plates):. PLATE AREA: All other factors being equal, greater plate area gives
