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.
What else can I help you with?
When does a capacitor discharge?
A capacitor discharges when it releases the stored electrical energy it has accumulated. This typically happens when the capacitor is connected to a circuit or load that allows the energy to flow out of the capacitor.
What type of energy is stored in a capacitor?
A capacitor stores electrical energy in the form of an electric field between its two plates when it is charged. This potential energy is released when the capacitor discharges, powering devices or circuits.
How does a capacitor connected to a battery store and release electrical energy?
A capacitor connected to a battery stores electrical energy by accumulating opposite charges on its plates, creating an electric field. When the capacitor is connected to a circuit, it releases stored energy by allowing the charges to flow back through the circuit, creating an electric current.
What is the capacitance energy formula and how is it used in electrical engineering applications?
The capacitance energy formula is given by the equation E 0.5 C V2, where E represents the energy stored in a capacitor, C is the capacitance of the capacitor, and V is the voltage across the capacitor. This formula is used in electrical engineering applications to calculate the amount of energy stored in a capacitor and to design circuits that require specific energy storage capabilities. Capacitors are commonly used in electronic devices to store and release electrical energy, and understanding the capacitance energy formula is essential for designing efficient and reliable circuits.
What is the significance of the current across a capacitor in an electrical circuit?
The current across a capacitor in an electrical circuit is significant because it determines how quickly the capacitor charges or discharges. This current flow is crucial for storing and releasing electrical energy efficiently in various electronic devices and systems.
When does a capacitor discharge?
A capacitor discharges when it releases the stored electrical energy it has accumulated. This typically happens when the capacitor is connected to a circuit or load that allows the energy to flow out of the capacitor.
What electrical component can hold a charge?
A capacitor is an electrical component that can hold an electrical charge. It stores energy in an electric field when connected to a power source and can release this stored energy when needed.
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.
What type of energy is stored in a capacitor?
A capacitor stores electrical energy in the form of an electric field between its two plates when it is charged. This potential energy is released when the capacitor discharges, powering devices or circuits.
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.
How does a capacitor connected to a battery store and release electrical energy?
A capacitor connected to a battery stores electrical energy by accumulating opposite charges on its plates, creating an electric field. When the capacitor is connected to a circuit, it releases stored energy by allowing the charges to flow back through the circuit, creating an electric current.

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.
Can the voltage across a capacitor change instantaneously?
No, the voltage across a capacitor cannot change instantaneously. It takes time for the voltage across a capacitor to change due to the storage and release of electrical energy in the capacitor.
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.
