Advantages and Disadvantages of Synchronous Motors

Synchronous motors play a crucial role in various industries, although their usage is relatively limited compared to induction motors. While induction motors are widely used because of their cheap prices, rugged construction, and low maintenance, synchronous motors offer unique advantages…

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…

EMF Equation of Transformer and Voltage Turn Ratio

Consider an AC voltage of magnitude “V” having frequency “f” is applied to the primary side of the transformer. ac flux Φm is set up in the transformer core, this flux links with the both primary and secondary winding of the transformer.…
