The way the capacitor functions is by acting as a very low resistance load when the circuit is initially turned on. This is illustrated below: Initially, the capacitor has a very low resistance, almost 0. Since electricity takes the path of least resistance, almost all the electricity flows through the capacitor, not the resistor, as the resistor has considerably higher

How Capacitors Work. A capacitor functions by storing charge using a dielectric material between two conductors or metal plates. When voltage is applied to a capacitor, charge builds up on the conductors, forming an electric field. These stored charges are then rapidly released to deliver the necessary surge of current when power is required. Types and Uses of
A capacitor is similar to a membrane blocking the pipe. The membrane can stretch but does not allow water (charges through). We can use this analogy to understand important aspects of capacitors: Charging up a capacitor stores potential energy, the same way a stretched membrane has elastic potential energy. As the capacity of a capacitor
Capacitor vendors have tried a number of approaches to prevent arcing. One of these is to apply a polymer or glass coating along the surface of the chip to fill any voids and provide a smooth surface that has a naturally lower susceptibility to creepage.
Each capacitor element is fused inside the capacitor unit. A "simplified" fuse is a piece of wire sized to melt under the fault current, and encapsulated in a wrapper able to withstand the heat produced by the arc during the current interruption. Upon the capacitor failure, the fuse removes the affected element only. The
High electric breakdown strength and high maximum but low-remnant (zero in the case of linear dielectrics) polarization are necessary for high energy density in dielectric capacitors. The high performance, multi-functionality, and high integration of electronic devices are made possible in large part by the multilayer ceramic capacitors (MLCCs
If the arcing occurs between a termination surface and through the dielectric material of the ceramic body to the first internal counter electrode, this usually causes a dielectric breakdown of the capacitor, resulting in a short-circuit condition that leads to catastrophic failure.
Capacitor vendors have tried a number of approaches to prevent arcing. One of these is to apply a polymer or glass coating along the surface of the chip to fill any voids and provide a smooth surface that has a naturally lower susceptibility to creepage.
Once the inception voltage of the ionized air is reached, a conductive path is created, allowing the energy in the concentrated electric field of the termination area to discharge. This discharge travels through the air along the surface of the capacitor and onto an area of lower potential rather than through the capacitor.
The capacitors act as a local reserve for the DC power source, and bypass AC currents from the power supply. This is used in car audio applications, when a stiffening capacitor compensates for the inductance and resistance of the leads to the lead–acid car battery. In electric power distribution, capacitors are used for power-factor correction.
Reservoir capacitors are used in power supplies where they smooth the output of a full or half wave rectifier. They can also be used in charge pump circuits as the energy storage element in the generation of higher voltages than the input voltage.
In electrical engineering, a capacitor is a device that stores electrical energy by accumulating electric charges on two closely spaced surfaces that are insulated from each other. The capacitor was originally known as the condenser, a term still encountered in a few compound names, such as the condenser microphone.
