Introduction Kirchhoff’s law is used to study the electrical energy used in a circuit. The movement of the charged particles is responsible for electric energy. Energy obtained from the kinetic energy or potential energy of the charged particles is the electric energy. Charged particles are atoms, molecules, or ions that have a charge on them.…

Introduction Gear generally refers to a special kind of machine element. In gear, the teeth are generally cut in a cone or cylindrical shape. These elements further help gear to transmit force and rotation from the driving shaft to the driven shaft. The profile of the gear tooth is the fundamental design of gear. Gears…

Introduction You are use electronics in your daily life from every small object to a big machine. The device by which you are reading this article is also a part of electronics. Electronics is a vast field that contains a huge amount of components like conductors, switches, circuits, diodes, processors, inductors, resistors, etc. All these…

Introduction Almost all forces in physics are characterized by an associated “field”. The idea, in layman’s terms, is to come up with a quantity that measures the strength of the source of the force. In physics, field refers to a physical quantity characterized by specific values at different points in space and/or time. It may…

Introduction The movement of electrons in an object provides the energy to do work. This energy is called electrical energy. The ratio of electrical energy absorbed is called an electrical power. There are many types of energy like electrical energy, mechanical energy, thermal energy, light energy, and wind energy. In our daily life, we get…

Introduction Resistance plays a major role in the study of electricity. Electricity is so important for various applications in our daily life. Electric current, which is the flow of electrons, passes through the electric circuit with the component’s resistor, capacitor, inductors are used. The electrical component resistor is used in the circuit to allow current…

Introduction Energy and work are measured in joules. By applying a force of one newton over a distance of one meter, an object is made to work (or to be energized). One joule is produced when an object is subjected to a force of 1 N and moves 1 m. Newton meters are used to…

Introduction Generally, we see when we put iron nails at some distance to the magnet, it gets attracted towards it. Why is that so? We see that certain materials have the capability to attract materials towards themselves. The materials are attracted to the field around the magnet known as the magnetic field. Like due to…

Introduction When a constant value of current passes through a conductor, the same ampere of current will flow in the conductor. The flow of current is the same, but the sections may differ in some parts. The flow of current is a macroscopic feature. Current The rate at which the electrons flow in a particular…

Introduction Physical qualities such as malleability, phase, texture, colour, polarity, solubility, and others let us distinguish the components around us. But, as we all know, another major classification of elements is based on their electric charge conductivity, i.e. (1) Conductors and (2) Insulators. Conductors An electrical conductor is described as a material that allows electricity…
