I Structure and Working Principle Field-effect transistors are divided into two categories: junction field-effect transistors (JFET) and metal oxide semiconductor field-effect transistors(MOSFET). According to the channel material type and insulated gate type, there are N channel and P channel tra...
Working Principle of a Bipolar Junction Transistor The working principle of both the NPN and PNP transistor is almost the same, both of them differ in the conduction of current through charge carriers based on the majority and minority of charge carriers. The NPN Bipolar junction Transi...
Once the switch S1 is closed in the circuit below, which of the following is true about the current through the resistor R1? Why voltage does not changes when connecting resistance in series? Explain. State the principle of a potentiometer and explain how is it used: a. to determi...
