When the current-carrying conductor placed in a magnetic field, it experiences a force due to the magnetic field on the other hand if the conductor moved into the magnetic field an emf gets induced across the conductor as per faraday’s…
Capacitor is a passive element in a circuit designed to store energy in the form of an electric field. besides resistor, capacitors are the most common electrical components. used mostly in electronics circuit, computers, power system. They are also used…
Armoured cable is a special cable that designed to give extra protection and reliability for wiring system. Generally armoured cable is used when cable may be subjected to harsh environment, or where there is risk of mechanical damage.This article explains…
This bridge was first introduced by Wheatstone for measuring the value of unknown resistance. Wheatstone bridge circuit consists of four resistors, two with known resistances P & Q and one known variable resistance R, and one unknown resistor X whose value…
What is the power factor and power triangle? In the modern electrical distribution system, most of the loads are inductive in nature like motor,transformer, electrical furnace. when induction motor run on no load or light load, create lagging power…
Definition: The difference between the true value and the measured value of the quantity is known as an error in measurement. The error in measurement can not be eliminated completely but it can be minimized. there are various types of…
The permanent magnet moving coil instruments (PMMC instruments) are suitable for DC quantity measurements only. PMMC instruments working principle based on Faraday’s law of electromagnetic induction states that when the current carrying coil is placed in the magnetic field it experiences…
There are many electrical components are used in the electronic and electrical circuit like a resistor, inductor, diode, transformer, capacitor, and many more. without these electrical components, the circuit is incomplete. each part has a different function in the circuit.…
In this article, we will explore the basics difference between AA and AAA battery, including their size, capacity,common uses and voltage. AA and AAA batteries are two common types of household batteries. The main differences between them are their size…
Zener Diode is a special type of diode that can conduct in forward as well as in reverse bias mode. This special diode is named after American physicist Dr. Clarence Melvin Zener. We will discuss working principles that underscore its…
