Wheatstone Bridge – Circuit Diagram, Working principle

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 is to be calculated. All four resistors are connected in a manner to form a […]

What is power factor and current? Power triangle

  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 factor. Reactive power is important because inductive loads required a magnetic field for functioning. Inductive […]

Types of Errors In Measurement Definition

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 errors in measurement. Calibration Errors Types of Errors in Measurement Base on the nature of […]

Induction Heating Working Principle-Applications

Induction heating is a process that utilizes Faraday’s law of electromagnetic induction to generate heat. A magnetic field is created by bypassing an alternating current (AC) through a coil. This magnetic field then induces eddy currents within the conductive material, causing it to heat up. Induction Heating Working Principle Induction heating is a process wherein […]

PMMC instrument-Working, Construction, Advantages

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 force and torque acting on the coil and it starts moving. Construction of PMMC Instrument […]
