Current stops going into a capacitor when it's voltage is equal to the supply voltage. From then there is no flow of current, so there is no magnetic field. Yet the capacitor remains charged and has energy to release if required.

What is the purpose of inductor?
The fundamental purpose of an inductor is to store electrical energy in a magnetic field.
What is the function of capacitance?
The main purpose of a capacitor is to electrostatically store energy in an electric field. It is originally known as condenser.
How does a capacitor act as battery?
Only in that it can store energy. However, the energy stored in a capacitor is usually very small, compared to a battery; and it can only hold the energy for a short time.
Do capacitors store electrical energy?
Capacitors act like tiny storage batteries made of two plates separated by a thin insulator or air. When one plate is charged negative and the other positive, they build up a charge that remains when the current is removed. When its power is required, the circuit is switched to conduct current between the two plates, and the capacitor releases its charge.AnswerCapacitors don't really store charge at all. They allow negative charge to be transferred from one plate to the other, thus establishing an electric field between their plates. But there is no net increase in charge -the amount of charge on the capacitor's plates, after 'charging', is exactly the same as there was before 'charging' -it's just moved around! What capacitors 'store' is energy, not charge.
What is an electrolic capacitor?
An electrolytic capacitor uses an electrolyte (ions in a solution) to store charges.
If the capacitor store the charge from the magnetic field then the capacitor is called?
it wouldn't store a charge from the magnetic field, only the current induced on the circuit would be stored
What is the purpose of capacitor in the circuit?
To store energy, in an electric field between separated charges. (An inductor stores energy in a magnetic field surrounding a current.)
What is the purpose of a capacitor in a circuit?
To store energy, in an electric field between separated charges. (An inductor stores energy in a magnetic field surrounding a current.)
What is held by power supply capacitor?
Capacitor store electrostatic energy in form of electric field.
Is that true a capacitor stores energy in the form of a magnetic field?
Simple answer: Yes. If there's electricity, there is a magnetic field. I'm guessing that you're thinking that alternating current reverses current flow, as opposed to direct current. This isn't quite right. A.C. works by alternately advancing and reversing the movement of charge, basically pumping electricity down a wire. Capacitors store charge. That's all they do until some part of a circuit lets them release it. So a capacitor connected to an a.c. source will just store charge and a magnetic field will certainly be attached.
What does a compacitor do?
A capacitor is a passive 2 terminal electrical component used to store energy in an electric field.
Do magnetic fields store energy?
of course, they do. A research project show that a motor constructed with magnets at specific directions & positions can run for atleast 100 years without break.But the magnets are not to be disturbed & also they don't have to be charged
How can electricity be stored?
In a way it can be. If a capacitor is connected to a battery, it will charge to the battery voltage. Then the capacitor can be discharged into a circuit to do work. But the capacitor doesn't store electrons, it stores an electrical field in the dielectric. If you mean storing the flowing electrons in a conductor, then they can't be stored except in a magnetic containment field such as in a cyclotron. A rechargable battery doesn't store electrons either, it stores energy in a chemical form which is converted to an electrical form when the battery is connected to a circuit.
What is the purpose of inductor?
The fundamental purpose of an inductor is to store electrical energy in a magnetic field.
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.
In which place an inductor store energy in it?
Because inductor forms a coil with magnetic field around it. It acts as a relay also. Tasleem
Why capacitor is used before UM66 in circuit for melody generator?
We used capacitor in UM66 because capacitors are used to store the energy, and hence when we press the switch it will charged the capacitor and energy stored in it, and after releasing the switch it releases the energy. So, we can use the capacitor to store the energy.
