Ampere`s Law
In electromagnetism, Ampère’s circuital law relates the integrated magnetic field around a closed loop to the electric current passing through the loop. In this article, let us learn in detail about Ampere’s Law. What is Ampere’s Law? According to Ampere’s law, magnetic fields are related to the electric current produced in them. The law specifies…

Laws Of Reflection
We know light is the form of energy which can undergo various phenomenons like refraction, reflection, diffraction, and interference. In this session, let us know more about laws of reflection (first law of reflection and second law of reflection), types of reflection, examples, differences, and total internal reflection. What is Law of Reflection? Definition: The…

Kirchhoff’s Law
Kirchhoff’s circuit laws lie at the heart of circuit analysis. With the help of these laws and the equation for individual components (resistor, capacitor and inductor), we have the basic tool to start analyzing circuits. In this article, we will discuss Kirchhoff’s current and voltage law and how to employ them in circuit analysis. History…

Doppler Effect
Doppler effect or Doppler shift is a phenomenon that is observed whenever the source of waves is moving with respect to an observer. For example, an ambulance crossing you with its siren blaring is a common physical demonstration of the Doppler Effect. In this article, let us understand the intricacies of the Doppler effect in…

Archimedes Principle
Archimedes principle deals with the forces applied to an object by fluids surrounding it. This applied force reduces the net weight of the object submerged in a fluid. In this article, let us familiarize ourselves with Archimedes principle. What is Archimedes Principle? Archimedes’ principle states that: “The upward buoyant force that is exerted on a…

Newton’s Laws of Motion
While Newton’s laws of motion may seem obvious to us today, they were considered revolutionary centuries ago. The three laws of motion help us understand how objects behave when standing still, when moving and when forces act upon them. This article describes Sir Newton’s three laws and a summary of what they mean. Newton’s First…

Ohm’s Law
Ohm’s law states the relationship between electric current and potential difference. The current that flows through most conductors is directly proportional to the voltage applied to it. Georg Simon Ohm, a German physicist was the first to verify Ohm’s law experimentally. One of the most basic and important laws of electric circuits is Ohm’s law.…

Current Electricity
What is Current Electricity? Current electricity is defined as the flow of electrons from one section of the circuit to another. Electromotive Force (EMF) and Voltage: When two bodies at different potentials are linked with a wire, free electrons stream from Point 1 to Point 2, until both the objects reach the same potential, after…

Work, Energy and Power
Work, Energy and Power are fundamental concepts of Physics. Work is the displacement of an object when a force (push or pull) is applied to it. We define the capacity to do the work as energy. Power is the work done per unit of time. This article discusses work, energy and power in detail. What…

Force
Aristotle famously represented a force as anything that causes an object to undergo “unnatural motion”. Sir Isaac Newton was one of the first scientists to study gravity and force. Any kind of force is just a push or a pull. It can be described as a push or pull on an object. What is Force? Push or…
