A capacitor can't deliver electrical energy 'constantly'. Much like a battery, electrical
energy can be stored in it, and then delivered later.
The capacitor only stores some definite amount of energy ... equal to 1/2 of its capacitance
multiplied by the square of the voltage to which it's charged ... and later, after it has
delivered that amount of energy, it delivers no more without being charged again.

Why is electric energy can not be stored?
Electrical energy is a form of energy derived from the flow of neutrons, the negatively charged particles in atoms. When loosely used to describe energy absorbed or delivered by an electrical circuit, "electrical energy" refers to energy which has been converted from electrical potential energy. This energy is supplied by the combination of electric current and electrical potential that is delivered by the circuit. At the point that this electrical potential energy has been converted to another type of energy, it ceases to be electrical potential energy. Thus, all electrical energy is potential energy before it is delivered to the end-use. Once converted from potential energy, electrical energy can always be described as another type of energy (heat, light, motion, etc.).
Does capacitance exist between two thin current-carrying conductors Explain?
The conductors of the transmission line act as a parallel plate of the capacitor and the air is just like the dielectric medium between them.A capacitor is a device used to store electrical charge and electrical energy.
What happens when dielectric is a conductor?
Yes possible. As a capacitor even with air as dielectric allows alternating current to pass through the capacitor filled with some material as dielectric would allow current to pass through it
What is the purpose of a dielectric in a capacitor?
Two functions - it provides electrical insulation, and it increases the capacitance, i.e., the amount of charge - and therefore also the amount of energy - that can be stored at a given voltage.
What is energy from separating charges?
If you mean separation of electrical charges, this involves potential energy. It is comparable, in a way, to gravitational potential energy. To separate the charges requires energy; if you bring them together again you gain the energy.
What is characteristic of power factor in capacitor?
Power factor characteristic in a capacitor is a measurement of how efficiently a capacitor uses electrical energy.
What is used to store potential electrical energy?
A Battery or a capacitor.
Why you use capacitors in power supply?
You use a capacitor to store electrostatic energy. You use an inductor to store electromagnetic energy. You use a resistor to dissipate electrical energy.
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.
What is metallic film?
A metal film capacitor is an electrical part that holds energy electrostatically inside of an electric field. The capacitor has a dielectric which separates two electrical parts which are made out of thin film.
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.
Purpose of a battery?
to crank the engine and then function as a capacitor for unused electrical energy when the alternator is running
What is the term used to describe the ability of a device to store energy in the form of an electrical charge?
Simply put, an electronic device that stores charge is a capacitor.
What is the functional operation of a single-phase capacitor start motor?
As with any motor the function is to turn electrical energy into mechanical energy.
What does a compacitor do?
A capacitor is a passive 2 terminal electrical component used to store energy in an electric field.
Why the flash of a camera is commonly powered by a capacitor?
Camera flashes use a capacitor because a capacitor can dump a lot of electrical energy very quickly. Much faster than a battery. That's how to produce a quick flash by using a capacitor that suddenly discharges the electricity.
Why the capacitor stores energy in the form of DC though it does not allow DC?
DC does not flow through a capacitor because there is no electrical connection between the plates; they are separated by an insulator calibrated for capacitance.
