The document discusses three widely used electronic components: resistors, capacitors, and inductors. Resistors are used to resist the flow of electricity and are measured in ohms. Capacitors are used to store electric energy and are measured in farads. Inductors are used to resist changes in current flow and are used to create magnetic fields. The document also provides information about an electronic component distributor called Express Technology Group.

1. Learn about the three most widely used
electronic components
Electronic components come in different types of shapes and designs. All of these components
have a unique and specific functionality. Each of them has their own importance and without
even one of them, a circuit won’t function in a proper manner. The circuit boards that are
usually seen in various electronic devices and computers are composed of multiple tiny
electronic components. These circuits are designed by a professional and experienced team of
electrical engineers. After selecting and soldering the appropriate electronic components into a
circuit board, the electronic devices and machines are built. They help control the working of an
electronic device.
If you are into electrical engineering or just simply curious about the different electronic
components then it’s better to learn about the working and purpose of each component. Below
mentioned are the three most widely used electronic components:
Resistors and variable resistors
A circuit board usually works by routing the voltage via the every electronic component
installed on it. The main reason behind it is to produce the required result. The capacity or
amount of voltage required differs from component to component.
Resistor is an electronic component that is designed to work as a poor conductor of electricity.
The ability to resist the current in a resistor is measured in Ohms. There are various types of
electronic resistors available in the market. The Variable resistor is termed as the
Potentiometer. An example of the variable resistor is: volume control knob mostly present on a
stereo. It is used to control the level of resistance.
Capacitor
A capacitor is designed using two metal plates which are separated by an insulator like
electrolytic, mylar and ceramic. Capacitors are electronic components that are basically used to

2. store electric energy. The capacitance of capacitors is measured in Farads. The voltage present
in it helps determine how much energy can be stored in it.
When there is flow of electrons from one plate to another, a capacitor is charged. Once the
capacitor is completely charged, the electric current in it automatically diminishes as the plate
can hold no more electrons. In this case, the capacitor’s voltage is exactly same as that of the
source.
Inductors
Inductors are used to resist the changes that happen in the flow of current. Direct current (DC)
flows in one direction while alternate current (AC) flows in any direction indefinitely. An
inductor is basically a coil of wires and it is used to create magnetic field. Once the power
supply is cut, the magnetic field collapses and the potential energy get released.
