AC Power Circuit Implied in Physics

In an alternating current circuit, power is defined as the amount of energy delivered by the circuit per unit of time. It is used to determine the total power needed to run a load. In the case of a DC circuit, voltage and current become constant. However, in an alternating current circuit, the instantaneous values […]

A Short Note on the Unit of Power

Power is a physical quantity in which energy transfers in a unit of time. It is a scalar quantity that has a magnitude but lacks direction. In physics, power is dependent on the amount of work done or energy transferred. It is also related to other quantities such as force, velocity, torque, angular velocity, current-voltage,

A Short Note on Properties of Non-Conservative Forces

There are two types of forces – conservative and non-conservative forces. If the work done by or against the force of moving the body depends only on the initial and final positions of the body and not on the nature of the path drawn between the initial and final positions, the force is said to

A Comprehensive Study on Electrical Energy, Power and Charge

When an electrical circuit generates energy, it does so by causing a reaction. Thermal, electromagnetic, mechanical and electrical are just a few examples of how this activity may occur. Batteries, generators, dynamos, photovoltaics, fuel cells, batteries, capacitors and magnetic fields may all produce and store electrical energy. As a result, electricity may be generated or

A Brief Note on Important Points about Power

In physics, power is a physical quantity related to work and energy. It is the rate at which energy is used. If a person does a different type of work, then the power required will also differ. When you push or pull an object by applying a force, there is some displacement seen. This is

Difference Between Kinetic Energy and Potential Energy

Energy is defined as the capacity to work. It exists in various forms like potential energy, kinetic energy, chemical energy, nuclear energy, electrical energy, etc. It can also be converted from one form to another.  For example, in solar cells, the light energy is converted into heat energy, which gets converted into electrical energy. Joule

Electric Potential Energy

Introduction When an object possesses electric potential energy, it is due to the combination of two factors: the charge possessed by the object itself and the relative position of the object with respect to other electrically charged objects. The magnitude of the electric potential is proportional to the amount of work required to move the

What is Potential Energy? Definition, Examples, And Types

Potential energy can be defined as the energy stored in an object due to the object’s relative position in a system with other objects. The system components that exert forces on one another of varying magnitudes depending on the component’s configuration, or relative location, will generate the potential energy. Potential energy of a system is

What is Non-Conservative force

The two general categories of forces in physics refer to conservative force and non-conservative force. Each type of force has distinct implications in physics and has many critical differences. In the case of conservative forces, the work done depends on the starting and end positions of the concerned objects. On the other hand, a non-conservative

Types Of Mechanical Energy

In very simple terms, mechanical energy is the energy owned by an object in a closed system due to its position or motion. The position contributes to potential energy and the motion is the kinetic energy of the object. Predominantly, the addition of the potential and kinetic energy gives the total mechanical energy in an
