What is Density? The density of material shows the denseness of that material in a specific given area. A material’s density is defined as its mass per unit volume. Density is essentially a measurement of how tightly matter is packed together. It is a unique physical property for a particular object. The principle of density… Continue reading Unit of Density

Unit of Force
We all know who Isaac Newton is and it was his research that led to the establishment of the popular formula F = ma representing acceleration and mass of an object when force is applied. While students can check the article on force in detail, here we will learn about the unit of force. Well,… Continue reading Unit of Force
Unit Of Pressure
Introduction: Pressure is usually defined as the amount of force applied to a certain area. The pressure is a physical quantity mainly expressed as the formula p = F/A, where F and A are force per area perpendicular to the surface. While we have already discussed everything about pressure in our earlier article, we will… Continue reading Unit Of Pressure

Uses Of Zener Diode
We are aware of the uses of Zener diode which is to permit the current flow in forward or reverse direction. Zener diode is a semiconductor device consisting of a P-N junction which conducts the current in reverse direction when a certain specified voltage is reached. It has a reverse breakdown voltage which means it… Continue reading Uses Of Zener Diode
Uses Of Transformer
Transformers are used to transfer current from one circuit to another without any physical contact between them and without changing the frequency or phase. There are various uses of transformer depending on the type. Some of the most common applications are mentioned below. According to the necessity, transformers are classified into: Power Transformers Distribution Transformers… Continue reading Uses Of Transformer
Uses Of Electricity
Imagining the world without any use of electricity is very difficult these days. Small things like study lamp to big things like a plane requires electricity to operate. Human civilization has become very modern, and electricity is needed everywhere. Here, some of the most notable uses of electricity on a daily basis are mentioned. Entertainment… Continue reading Uses Of Electricity
Uses Of Electromagnet
An electromagnet is a kind of magnet where the magnetic field is created by an electric current. The uses of electromagnets are given here to help learners understand the topic more effectively. Electromagnets can be considered as a temporary magnet that functions with the help of an electric current. The magnetic strength of an electromagnet… Continue reading Uses Of Electromagnet
Uses of Inductor
What is Inductor? An inductor is defined as a passive component that is used in most electrical circuits to store energy in the form of magnetic energy when electric current flows through it. It is also known as the coil, choke, or reactor. It is a two-terminal electrical component that is characterized by its inductance.… Continue reading Uses of Inductor
