Construction of wire wound potentiometers
The basic construction of wire wound potentiometer is made of nichrome wire wound on a doughnut-shaped core of bracket and enclosed with an insulating coating. A window is left in the insulating cover, which exposes the resistive
What is junction field effect transistor (JFET)?
The junction field effect transistors (JFET), is a type of field effect transistor (FET). They are three terminal unipolar solid state devices that can be used as voltage controlled resistors or electronically controlled switch. An N-type JFET
