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…

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…

Induction Heating

Induction heating is a process that utilizes Faraday’s law of electromagnetic induction to generate heat. By passing an alternating current (AC) through a coil, a magnetic field is created. This magnetic field then induces eddy currents within the conductive material,…

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…
