What is a Field Effect transistor (FET) ?

These types of transistors control and determine the shape and size of the channel based on the unipolar voltage. In fact, FET transistors perform the role of voltage control. Field effect transistors have much less energy consumption and heat loss than connected bipolar types. Also, the amount of noise and sound of these transistors and the amount of their input impedance is higher .......

Please do not change pictures fast in film and when you explain a component fix on real picture of that component
