Question

How much energy can a capacitor store?

Answer 1

Hint: A capacitor is a two-terminal electrical component. They are one of the most basic passive components we employ, along with resistors and inductors. You'd have to dig hard to locate a circuit that didn't have a capacitor. Capacitors are unique in that they can store energy, similar to a fully charged electric battery. Capacitors, or capacitors, are used in a variety of crucial circuit applications. Local energy storage, voltage spike suppression, and complicated signal filtering are all common applications.

Complete answer:
The energy is stored in a capacitor used in dramatization. That is generally seen in movies where medical personnel utilizes a defibrillator to deliver an electric current through a patient's heart to get it to beat. The usage of capacitors in microelectronics, such as handheld calculators, is a less dramatic application of the energy stored in the capacitor. The energy stored in a capacitor and the formula used to determine the energy stored in a capacitor.
The energy held in a capacitor is the electric potential energy, which is proportional to the capacitor's voltage and charge. When a conductor's capacitance is \[C\], it is originally uncharged and when connected to a battery, it obtains a potential difference \[V\].
The formula for the energy stored in a capacitor is:
$U = \dfrac{1}{2}C{V^2}$
Where,
\[U\]- the electric potential energy stored in the capacitor measured in Joules.
\[C\]- capacitance of the capacitor,
\[V\]- potential difference.


Note:
Capacitor Energy's Applications
Here are a few examples of how capacitor energy is used:
A defibrillator administers a strong shock to a person's heart in a short burst to rectify an irregular heart rhythm. Large electric current shocks are used to interrupt the arrhythmia and allow the body's natural pacemaker to return to its regular rhythm. The energy stored in the capacitor is used by a defibrillator.
The energy held in the capacitors used by audio equipment, uninterruptible power sources, camera flashes, and pulsed loads such as magnetic coils and lasers.
Supercapacitors can store a vast quantity of energy and perhaps open up new technological possibilities.
