An induction motor is a generally used AC electric motor. In this motor, the electric current required within the rotor to generate torque is attained through electromagnetic induction from the stator winding’s rotary magnetic field. The rotor of this motor can be a wound type or squirrel cage rotor. Induction motors are also called ‘asynchronous motors’ because they operate at a less speed as compared to their synchronous speed. There are different types … [Read more...]
What is a Power Triangle : Formula and Its Working
Generally, power is the capacity to do work. In the electrical domain, electric power is the amount of energy transferred to some other form per unit of time like light, heat, etc. Mathematically, it can be defined as the product of voltage and current. Consider the DC circuits, which have only one voltage source either a voltage source or a current source, so the capacitors work as an open circuit within a steady-state whereas the inductors work like a … [Read more...]
What is a 7805 Voltage Regulator : Working & Its Applications
All voltage sources cannot provide stable output because of fluctuations within the circuit. For obtaining stable output, the voltage regulator is implemented. A voltage regulator is used to create and maintain a stable output voltage which is used for DC/DC power conversion, some can perform AC/DC or AC/AC power conversion. The integrated circuits or ICs which are used for voltage regulation are known as voltage regulator ICs. There are different types of … [Read more...]
What is Moving Coil Galvanometer : Working & Its Applications
The first moving coil galvanometer was invented in 1820 by Danish physicist Hans Christian Oersted as an improved version of the astatic galvanometer he had created a few years earlier. Since then, the design has been modified and improved to become smaller, more accurate, and more sensitive. The instrument is still widely used today in laboratories and factories all over the world for all types of electrical measurements. This article discusses an … [Read more...]
Step Down Transformer : Working & Its Applications
A Transformer is a static electrical device because it doesn’t have moving parts. The main function of a transformer is to change the electrical power from one electric circuit to another by changing voltage & current but not changing frequency. Transformers are classified into two types based on their function as a step-up transformer and step-down transformer. This article discusses an overview of a step-down transformer and its working with … [Read more...]
What is Tesla Turbine : Design & Its Efficiency
Initially, a steam turbine is a kind of device which is available in the form of a heat engine. This turbine receives most of its development in the thermodynamic efficiency by using various levels in the steam expansion that outcomes in a similar approach like reversible expansion procedure. This is the very basic principle of the turbine. The first device that was originated in the classifications of turbines is a steam turbine which is very compact like … [Read more...]
What is Tesla Coil : Working Principle & Its Applications
Before the invention of the Tesla coil, air-core transformers and electrical oscillations were introduced and the first invention of the tesla coil was done by Thomson Elihu in the year 1889, then after the patent rights for tesla coil was gained by Tesla in 1891. The first-tesla circuit came to known to the public as having the elements of the capacitor, high voltage transformer, spark gap, and oscillation transformer. At present, tesla coil devices … [Read more...]
What is Surge Arrester : Working, Types & Its Applications
With the evolution of the electric grid concept, engineers understood that new equipment is required for the protection of high-level voltage power devices. Devices like electrolytic arresters came into evolution during the period 20th century which is appropriate for high power requirements. Comparatively, the short-lived technology came into existence in the next 20 years. The contemporary word arrester was initially used in the period the mid-1800s … [Read more...]
What is a Form Factor : Peak Factor & Its Derivations
At the time when the supply of heaters and motors took place, the power stations provided a good sinusoidal signal voltage, and the load receives a sinusoidal wave current. The entire system is manufactured in the way to manage this signal where this seems to be ideal for efficient distribution. But there happened one issue which was that the transmission system brought in magnetizing current along with the load current. This led to the situation that … [Read more...]
What is Nodal Analysis : Features & Its Examples
We know that the electric domain is huge, and it all turns around electrical circuits and networks. So, analyzing an electric circuit is sometimes simple and in some cases, it turns to be too complex because we need to find out unknown voltages and current values at every node in the circuit. In order to make the circuit analysis process easy, there were mainly two approaches which are mesh and nodal analysis. Both techniques make the process of analyzing … [Read more...]
