At present, electrical energy is a significant resource, so it is increasing day by day. When electrical demand increases, then the distribution system should have sufficient capacity to meet that demand. So this capacity is measured by engineers with the demand factor (Df) formula. It is a very significant factor for engineers, homes, businesses, etc. Generally, it is measured every month but most companies choose to measure it periodically at shorter … [Read more...]

Electron Flow : Working, Formula & Its Differences
An Electron (e–) is a subatomic particle with a negative electric charge where the atom is made with three particles like protons, electrons & neutrons. All these three particles can form the nucleus of an atom. Every electron carries 1 unit of negative charge like 1.602 x 10-19 coulomb & it has an extremely small mass like 9.10938 x 10-31 kg as compared with a proton and a neutron. An Electron belongs to the first invention of the lepton particle … [Read more...]
Coefficient of Coupling : Derivation, Working & Its Example
For inductor-coupled circuits, the coefficient of coupling is a significant factor to decide the amount of coupling between the inductively coupled coils. These coils are coupled with the magnetic flux. If one inductor’s total magnetic flux is coupled with the other inductor then it is known as perfect coupling. In this situation, this coupling (K) is expressed as 1 which means 100% coupling. The mutual inductance mainly depends on the coefficient of … [Read more...]
Different Types of Resistors and Its Color Code Calculation
The resistor was invented in 1827 by a mathematician namely “Georg Simon Ohm” at the University of Erlangen. After that, he published several research papers on the transmission of heat within molded circuits & also invented the “ohm law”. After this law invention, there are many types of resistors were developed. At present, we are using different types of resistors in so many electrical and electronic applications. This article provides brief … [Read more...]
Eddy Current : Working, Advantages, Loss, Braking System & Its Applications
We know that electromotive force & current will generate when the magnetic flux is flowing throughout a coil changes. Similarly, once the magnetic flux is passed throughout a solid coil, then it will induce current & emf. So the induced current through the conducting body is called the eddy current. This current is named an eddy current because of the flow of the current look like eddies/whirlpools. This article discusses an overview of an eddy … [Read more...]
Voltage Follower : Circuit, Working, Purpose & Its Applications
The operational amplifier or op-amp is a versatile & very efficient device. The op-amp is used to amplify the weak signal and it can be made simply into various forms based on the requirements of the circuit. One of the forms is the voltage follower. Here voltage follower is mainly used for isolating the signal as well as improving load capacity and this is also known as a unity-gain amplifier, isolation amplifier, or buffer amplifier. In a voltage … [Read more...]
Phase Shifting Transformer : Construction, Working & Its Applications

Compared to fixed power transformers, these are extremely … [Read more...]
Non Inverting Op Amp : Circuit, Working, Derivation, Types and Applications
An operational amplifier which is termed a high gain, DC coupled, inverting feedback amplifier was initially observed in the year 1941 by Karl D. Swartzel. In this configuration, the amplifier is designed using three vacuum tubes which results in a gain of 90 dB, and it functions in the voltage range of ±350 volts. This operational amplifier was just a single inverting type of amplifier and does not have differential inverting and non-inverting inputs. … [Read more...]
Shunt Reactor : Working, Types, Characteristics & Its Applications
A reactor or line reactor is a coil, used to protect the electrical devices & power transformers from the generated reactive currents throughout the fault conditions within the transmission. This reactor is generally made with an inductive material. The main function of the reactor is to restrict the reacting current that can harm the power transformer throughout the distribution or transmission within the substation. There are different types of … [Read more...]
