Is capacitor a conductor?
A capacitor (originally known as a condenser) is a passive two-terminal electrical component used to store energy electrostatically in an electric field. The forms of practical capacitors vary widely, but all contain at least two electrical conductors (plates) separated by a dielectric (i.e., insulator).
This time it's called electrical potential energy. And this, if you've not guessed by now, is the energy that a capacitor stores. Its two plates hold opposite charges and the separation between them creates an electric field. That's why a capacitor stores energy.
- When charge enters into one terminal of a capacitor, an equal amount of charge leaves the other end. But capacitors do store electric energy. The energy is stored in an electric field. Voltage, when applied between two plates of a capacitor, creates a potential difference between its plates.
- Purpose of a capacitor is to keep negative & positive charges separated from each other. The two different charges are held on two different plates which are separated by an insulator. presence of capacitor in an AC circuit changes the phase angle between voltage and current.
- Because inductors store the kinetic energy of moving electrons in the form of a magnetic field, they behave quite differently than resistors (which simply dissipate energy in the form of heat) in a circuit. Energy storage in an inductor is a function of the amount of current through it.
That depends on the type of capacitor it ranges from quality. Some can store it just a few seconds. While super capacitors have been able to store up to 50% of its energy for 30-40 days.
- If an ideal capacitor is charged to a voltage and is disconnected it will hold it's charge. In practice a capacitor has all kinds of non-ideal properties. Capacitors have 'leakage resistors'; you can picture them as a very high ohmic resistor (mega ohm's) parallel to the capacitor.
- A resistor is a passive two-terminal electrical component that implements electrical resistance as a circuit element. In electronic circuits, resistors are used to reduce current flow, adjust signal levels, to divide voltages, bias active elements, and terminate transmission lines, among other uses.
