Transformers are a vital part of our electrical grid. They allow us to convert electricity from one voltage level to another, and they play a huge role in transmitting power over long distances. In this blog post, we will discuss the working principle of a transformer and how it is able to transfer electrical energy […]

Work, Energy, and Power: Introduction Living beings must perform several life processes to survive. Work, Energy, and Power are the main criteria dependent on each other to carry out these processes. The energy for these processes comes from food. Work can only be done if a force is applied and there is motion or displacement

The moment of inertia of a rigid body may be defined as the minimum amount of torque required by the body to rotate in the given angular momentum. However, the moment of inertia is calculated for a given axis and changes concerning the rotation axis. For calculation purposes, the moment of inertia is depicted. The

Wave motion is associated with the disturbances that propagate from an inertial state of rest or equilibrium and attains a significant state of motion. It moves from one point to the other in an organised manner. The most prominent wave motion can be noticed in the water bodies through the ripples and tides. Wave motion

A Wheatstone bridge is an electrical circuit. It is used to find an unknown electrical resistance by balancing two legs of a bridge circuit. One of the two legs contains an unknown resistance. The main advantage of the circuit is its ability to provide very accurate measurements. It was invented by Samuel Hunter Christie in

If we take any charged coil, it will have both an electric current flowing through it, as well as a magnetic field around it. This magnetic field opposes the flow of current in the coil, and following Faraday’s Law, creates an emf or electromotive force in the coil. The coil basically has a voltage across

Momentum is the physical quantity that is also a vector quantity. Momentum has come up from its origin word “Moment”. When we hear the word “moment”, we get a little idea about the relation between time and some kind of motion, or we can say motion that is dependent on time. Since the word “momentum”

Simple harmonic motion (SHM), is an oscillation. This model illustrates how masses oscillate about equilibrium points in real life. A mass on a spring is an example of such a situation. Physicists call this simple harmonic motion the motion back and forth through an equilibrium or central position, where one side’s maximum displacement is equal

Van der Waals Equation (or Van der Waals equation of state) helps us in understanding the behaviour of real gas. It is used extensively in chemistry and thermodynamics. In 1873 Johannes Van der Waals formulated this equation. This is basically an upgraded version of the ideal gas law. If you have heard about this equation

The MOI of a rigid body, also recognized as its mass moment of inertia, angle mass, 2nd MOI, or, extra accurately, rotational I or inertia, is an amount that determines the force applied for a desired rotational motion about a rotational axis, in the same way that mass defines the force required for the desired
