What is knee point or cut-in voltage of PN junction

The minimum amount of voltage required for conducting the diode is called knee voltage and it is also known as cut-in voltage. before knee voltage diode behave like a high resistor(means it’s not conduct).knee voltage is different for different elements for e.g for Si knee voltage is 0.7v, knee voltage is Ge 0.3v. To know more about knee or cut-in voltage, you may read below article.Read More:…See More

Why induction motor is called asynchronous motor?

The induction motor function if there exist slip between the synchronous speed and the actual speed of the rotor. The rotating magnetic field rotates at the synchronous speed in the air gap, however the flux that links to the rotor conductor has less speed than synchronous speed, The difference between the speed is called slip.The slip cause current to flow in the rotor conductor and as a result torque is produced. That is why an induction motor is called asynchronous ( a= Not, Synchronous= Not…See More

Why CT secondary should not be left open?

During normal operation of CT, the primary and secondary winding produces mmf which by lenze’s law opposes each other. As the secondary mmf is slightly less than the primary mmf, the net mmf is small. This net mmf is the working/magnetizing mmf of the core of CT.Now, in case secondary winding is kept open, then secondary current will be zero while the primary current of CT will remain same. Therefore the opposing mmf of secondary will no longer exist. Hence the net mmf is due to primary current…See More

on what factors eddy current loss depends- Eddy current loss formula

Posted on May 23, 2021 at 4:12am 0 Comments

The eddy current loss of transformer depends on the following factors.

  • Supply Voltage
  • Supply frequency
  • Thickness of the volume
  • Volume of core material
  • Resistivity of the core material…

Why is Core of the transformer laminated?

Posted on May 23, 2021 at 4:05am 0 Comments

To minimize the eddy current losses, the iron core is formed using several thin electrically insulated sheets called lamination.

The current flowing in the sheet is equal to;

I= Potential…

CRGO Core for Transformer - Why? & Its advantages

Posted on May 23, 2021 at 3:57am 0 Comments

C.R.G.O (Cold Rolled Grain Oriented) core is used in transformers to reduce eddy current losses and increase corrosion resistance. It also contributes to a reduction in coercive force resulting in a decrease in the loss of reverse magnetization in transformers.

Good Day,

How is everything with you, I picked interest on you after going through
your short profile and deemed it necessary to write you immediately. I have
something very vital to disclose to you, but I found it difficult to express
myself here, since it's a public site.Could you please get back to me on:
(mrsstellaabudheir200@gmail.com ) for the full details.

Have a nice day

Thanks God bless.

Stella.
