We all should know besic concept and law of Electrical system.
Here just three besic question answer is given by me.
What is Solid State relay ?
What is retentivity ?
What is Field and Armeture winding
2. What is Retentivity?
It is the effect which we see in soft ferromagnetic material.
When magnetic flux pass through it. It behaves like magnet
and when we cut magnetic flux,it loses magnetism property.
But in reality there has some magnetism present in this
material. This effect we call Retentivity or Residual
magnetism.
3. What is Field winding and
Armeture Winding ?
Armeture Winding :- This Winding where flow current. It behaves
like current carring conductor.
Field winding :- This Winding where produce magnetic field when
we give current
4. What is Solid State
Relay?
It is used to switching purpose for both ac,dc current
by using an SCR,TRIAC instead of mechanical No/Nc
contact.
