Ohms law says that the current running through the conductor is directly proportional to the potential difference across its extremities as long as the temperature and other physical conditions are constant. Formula of Ohm’s Law Ohms law formula is articulated as V=IR WhereVoltage is V and is measured in Volts, The current flowing through the conductor… Continue reading Ohm’s Law Formula
Law of Conservation of Energy
Energy is required for the evolution of life forms on earth. In physics, it is defined as the capacity to do work. We know that energy exists in different forms in nature. You have learned about various forms of energy – heat, electrical, chemical, nuclear, etc. In this article, we will learn about the laws… Continue reading Law of Conservation of Energy
Newton`s Second Law Of Motion
What is Newton’s Second Law of Motion? Force is equal to the rate of change of momentum. For a constant mass, force equals mass times acceleration. Defining Newton’s Second Law of Motion Newton’s second law states that the acceleration of an object depends upon two variables – the net force acting on the object and… Continue reading Newton`s Second Law Of Motion
Newton`s Laws of Motion – First Law
What is Newton’s First Law of Motion? Newton’s first law of motion states that a body remains in the state of rest or uniform motion in a straight line unless and until an external force acts on it. Putting Newton’s 1st law of motion in simple words, a body will not start moving until and unless… Continue reading Newton`s Laws of Motion – First Law
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 the magnetic field that is associated with a given current or vice-versa, provided that the electric field doesn’t change with time. Ampere’s Law can be stated as: “The magnetic field created by an… Continue reading Ampere`s Law
Coulomb`s Law
What is Coulomb’s Law? According to Coulomb’s law, the force of attraction or repulsion between two charged bodies is directly proportional to the product of their charges and inversely proportional to the square of the distance between them. It acts along the line joining the two charges considered to be point charges. coulomb’s Law Formula In… Continue reading Coulomb`s Law
