Electric potential and potential difference are two different things. The main difference between electric potential and potential difference is that electric potential is defined at a point whereas the potential difference is defined between two points. Let see in detail the differences based upon definition, formula, unit, etc. Difference between Electric Potential and Potential Difference … Read more
Proton and neutron are the particles that are found at the center of an atom and both particles comprise the nucleus. Apart from electrons, protons and neutrons form the nucleus of an atom. In this article, we will discuss what is the difference between proton and neutron. Difference between Proton and Neutron in tabular form … Read more
A scanner is an input device that can scan different types of documents like photographs or a text page. While the process of scanning goes on the document is converted into a digital format which creates an electronic version of that document. This document can hence be viewed and edited on a computer. There are … Read more
Resistance is generally a force that opposes the motion of a body and slows down the performance of the body. In the field of electrical and electronics, the resistance is the opposition offered by the material to the flow of current through it. The S.I. unit of resistance is ohm (Ω). The effect of temperature … Read more

Smoke detectors are very popular electronic device which are used to detect the presence of smoke in the surrounding, indicating the possibility of fire. Hence, these are very important in prevention of mishaps due to any fire accident. These devices are present almost in all infrastructures ranging from small restaurants to big buildings and government … Read more
Biot Savart Law is used to determine the strength of the magnetic field at any point due to a current-carrying conductor. This law is given by two physicist Jean-Baptiste Biot and Felix Savart. Hence this law is known as Biot Savart Law. This law is of fundamental importance and can be verified experimentally. Consider a … Read more
In this article, we will see Star Delta Conversion and Delta Star Conversion. This conversion is widely used in the analysis of 3-phase electric power circuits. In simple words, it is used for the simplification of an electrical circuit in order to easily analyse the circuit. Star Delta Conversion In this section, we will see … Read more
The amount of charge flowing through any cross-section of a substance in a unit time is called Electric current. It can also be defined as the rate of flow of charge through any cross-section of a substance. If the electric current does not change with time, then electric current, i = q/t where q = … Read more
You might have gone through the term open circuit while solving electrical circuits. Lets see what is a open circuit in electrical circuits. When any element between two terminals is removed then it is called as open circuit between two terminals. The current in an open circuit is always zero regardless of the voltage across … Read more
