How defibrillators work explained simply
Defibrillators often need to be carried to the patient (i.e. need to be portable) so they often use batteries as source of power. The step up transformer is able to raise the battery voltage to charge the capacitor (e.g. from 12 V to 2000 V).
Why do we use capacitors and not batteries in defibrillator?
In a portable defibrillator (or a taser!) a battery charges a capacitor, then the capacitor releases the the charge into the subject much, much faster than it could have been supplied directly from the battery. The very large capacitors used in defibrillators can (briefly) supply 2000 to 6000 volts.
Capacitor in Electronics – What It Is and What It Does
A capacitor is an electrical component that stores energy in an electric field. It is a passive device that consists of two conductors separated by an insulating material known as a dielectric. When a voltage is applied across the conductors, an electric field develops across the dielectric, causing positive and negative charges to accumulate on the conductors.

These drawbacks make it challenging to use capacitor batteries as a primary power source for electric ...
Which Capacitor Types Should You Use? | Blogs
Capacitors are one of the main components in all electronic devices and are vital to their operation. In modern electronics, you will most commonly find ceramic capacitors decoupling power supplies for almost every integrated circuit (IC) on a circuit board or aluminum electrolytic capacitors as bulk capacitance for a voltage regulator.However, capacitors are …
Basic 5 Volt Power Supply : 20 Steps
The capacitors help filter the input and output from noise created by the power supply, and/or the load (i.e your project). We will add larger capacitors on both sides, to help keep our power supply clean, and noise free. Secondly, there is …
Basic 5 Volt Power Supply : 20 Steps
The capacitors help filter the input and output from noise created by the power supply, and/or the load (i.e your project). We will add larger capacitors on both sides, to help keep our power supply clean, and noise free. Secondly, there is no way of knowing if our power supply is working, so we will add a little LED as our power indicator.
batteries
Other answers talk about practical use of capacitors for energy storage, but in theory, capacitors and batteries are very different. An ideal capacitor is a circuit element with the property that the voltage across its terminals is proportional to the integral of the current that flows through the device:
Introduction to Capacitors, Capacitance and Charge
There are many different kinds of capacitors available from very small capacitor beads used in resonance circuits to large power factor correction capacitors, but they all do the same thing, they store charge. ... capacitance of a capacitor while keeping its size small is to "interleave" more plates together within a single capacitor body ...

High-voltage capacitor in a low-voltage system
A leaky capacitor has the effect of a large rated capacitor that leaks and keeps the circuit from working properly. In most cases, you can over rate a capacitor and get away with it. If you double the voltage value of the capacitor but keep the supply voltage low you might want to also double the Farad value.
