Why is rectified voltage storge in a capacitor?
Because a capacitor is ideal for storing energy over short periods, as in a reservoir capacitor in a power supply.
What is capable of storing electrical energy in an electrostatic field?
condenser
What is the total capacitance of this arrangement the charge of each capacitor and the voltage across the last capacitor and the energy stored in it?
(a) what is the total capacitance of this arrangement (B) the charge stored on each capacitor (C) the voltage across the 50 micro farad capacitor and the energy stored in it. 20v and 20+30+50 micro farad
What is capacitor function?
The capacitor is used to store the charge applied to it.This stored charge can be used to absorb voltage spikes and voltage drops.AnswerIt's a misconception that a capacitor stores charge. In fact, it stores energy. The net charge on a fully-charged capacitor is the same as on a fully discharged capacitor.
What is the purpose of a variable capacitor?
Capacitors are circuit devices for storing electric energy. Variable capacitors are mainly used in filter circuits and power supplies. They are used in a variety of appliances.
Can a generator store electricity?
Nope, it just creates it. A Battery or a Capacitor is capable of storing energy.
What is meant by capacitor charging problem?
storing of energy
What does a capacitor?
Capacitor is an arrangement for storing large amounts of electric charge and Hence electric energy in a small space.

What is capable of storing electrical energy in an electrostatic field?
condenser
What the heck is a capacitor used for?
Very roughly speaking, it used for storing energy in its electric field.
How do you save light energy?
By converting it to electrical energy and then chemical energy through photovoltaic cells and storing in some form of battery or capacitor.
Why is the asthenosphere not capable of storing elastic energy?
astic energy can only be stored in cold, brittle rocks.
What is the total capacitance of this arrangement the charge of each capacitor and the voltage across the last capacitor and the energy stored in it?
(a) what is the total capacitance of this arrangement (B) the charge stored on each capacitor (C) the voltage across the 50 micro farad capacitor and the energy stored in it. 20v and 20+30+50 micro farad
As capacitance means the ability of storing charge then its unit should be Joule then why you called its unit farad?
I hear you saying that "joule" should be a unit of "ability"; that's pretty slippery."Joule" is a unit of energy. The capacitor does store energy.The energy stored in a capacitor is [ 1/2 C V2 ], measured in joules.' C ' is the capacitance, in farads.' V ' is the voltage across the capacitor, in volts.You can see that a larger capacitance (more farads), when charged to a smaller voltage,stores the same amount of energy. So the joules of energy stored in the capacitordepends on the capacitance and the voltage across it.The same energy can be stored in capacitors with different values of capacitance.In fact, the same capacitor can store different amountsof energy ... more or less joulesat different times.
What is difference between capacitor and cell but both are energy storing elements?
A cell produces a DC current and keeps on producing it until the cell is depleted, wheras a capacitor stores electrical energy and discharge's it all when needed and becomes empty until it is recharged. In a nutshell a cell produces electrical energy and a capacitor only stores it.
In a tank circuit why can be the energy across the inductor and that of the capacitor not be equal?
When an LC tank is excited at the resonant frequency, the energy across each will be equal (but not necessary equal at a given moment in time). If excited at a frequency other than the resonant frequency, the impedance of the inductor (wjL) and capacitor (1/wjC) will not be equal, therefore energy across each will be different.
