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…
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…
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.…
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…
All electrical devices run on electrical power, the consumed energy is measured in terms of watts. the device used to measure consumed power is called a watt meter. to measure three-phase power mainly two methods are used namely two wattmeter…
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…
Relays are integral components in modern electrical systems, acting as electronic switches that manage high-voltage circuits with low-voltage signals. Understanding their construction and operation is essential for anyone working with these devices. Basics of Relays Relays function as electronic switches,…
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…
In the Delta connection, the dissimilar terminals of three phase windings are connected together. The finishing end of one phase is joined to the starting end of the other phase to obtain mesh or delta-connected winding. Delta connection in the…
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…
