Capacitors are one of the most fundamental components we use for influencing the behavior of electric circuits. Capacitors can be used for storing energy, conducting alternating current (AC), and blocking or separating direct current (DC). There are many types of capacitors out there that are differentiated by the materials used in construction, each providing certain benefit features which make it better for some applications. Understanding basic capacitor construction and how different materials can affect their characteristics will give you a help with choosing the proper capacitor for your projects. They can be divided into two basic groups: electrostatic capacitors and electrolytic capacitors.
Electrostatic capacitors have symmetrical non-polar terminals. Material such as plastic film and ceramic are used as the dielectric, while electrodes can be made from a
Resistor is a substance which has ability to oppose the electric current to flow through. In other words, resistor is used to limit current and divide voltage in a practical circuit. There are two types of resistors we commonly see around us, one is Linear Resistors another one is Non-linear Resistors. The difference between linear resistors and non-linear resistors is that linear resistor is with a constant resistance while non-linear resistor is with non-constant resistance.
Resistance is used to represent the value of resistors mentioned above. People named the unit of resistance after ohm that in order to in honr of the German physicist Georg Simon Ohm for the contribution to the discovery of Ohm’s Law. It is often denoted by the Greek symbol Ω
In this content we only discuss about Linear Resistors
