A Simple Guide to Comprehend 6 Electronics Components

Are you interested to learn “How electronic components actually work?” This post teaches you 6 Electronic components in the simple and practical way thus making the subject easier. The section below provides a basic introduction to these components. The latter part explains contains the simple video guide on electronic components.


The resistor is an electrical component which is used to control electric current flowing through a circuit. Ohm’s law defines voltage through any circuit as a product of current and resistance.
V = IR
For a constant voltage, the resistance is inversely related to the current. This property of resistors is used to reduce or increase the current flow.


The capacitor is an electric component which is used to store the charge. It contains two parallel plates which are separated by a dielectric medium.


A diode is a passive electrical component which allows the flow of current in one direction. A diode is made of a single PN junction. The normal diode is employed in rectification process (a method to convert alternating current to direct current). Whereas LED or light emitting diode emits light during its working.


A transistor is made up of two PN junctions. Our consumer electronics and gadgets might contain thousands or even millions of transistors on their bodies.

Ohm’s Law

Ohm’s law is a fundamental law of electrical engineering which explains the relationship between current and voltage in electrical circuits.

Resistor color coding

It is a technique which is used to indicate values of resistors by using different color bands over their bodies.
Let’s understand these concepts in detail below:
