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…

Introduction Have you seen a bolt of lightning before a thunderstorm on rainy days? Did your elders tell you not to touch electronic devices with wet hands? You must have seen electronic appliances like a television, refrigerator, air conditioner, and mixer at your home. Do they work automatically? Or do they need some energy to work? Yes. This…

Introduction Carbon resistors are a type of resistance component used in electrical and electronic circuits to provide resistance to the flow of electricity, generally as a way to regulate current or voltage. There are multiple types of carbon resistors and each type has different features, functions, and uses that it performs well. Graphite or coke,…

Introduction Ampere Prefixes are commonly used while studying electrical circuits. There are seven fundamental units i.e. metre(m), kilogram (Kg), second(sec), Ampere(A), Kelvin(K), mole(mol), and Candela (Cd). Among these basic units, Ampere(A) is used to denote the flow of current. It is also noted shortly as the amp. There are many systems of units used such as the KGS…
