Explain Transistor Current Components: The various transistor current components which flow across the forward-biased emitter junction and reverse biased collector junction are indicated in Fig. 10.11. The current flowing into…
Important Points Regarding Working of Transistors: The noteworthy points regarding working of transistors are summarized below. 1. Current conduction in N-P-N transistor is by electrons and the conventional current flow…
What is Transistor Biasing? - Types of Biasing As already mentioned, for normal operation of a transistor emitter-base junction is always forward biased and collector-base junction is always reverse biased.…
Transistor Action : Operation of PNP Transistor: Transistor action - Transistors of both types (P-N-P and N-P-N) behave exactly in the same way except change in biasing and majority carriers.…
Transistor Terminals (Emitter, Collector and Base): As mentioned already, transistor is a single crystal in which there are two P-N junctions, as shown in Fig. 10.1. The idea behind is…
Transistor Construction: The transistor construction consists of a silicon or germanium (preferably silicon because of its smaller cutoff current ICBO, smaller variations in ICBOÂ due to variations in temperature and higher…
Phototransistor Construction and Working Principle: The sensitivity of a photo diode can be increased by as much as 100 times by adding a junction, resulting in an NPN device. A…
Unijunction Transistor in Static Relay: Unijunction Transistor in Static Relay is a three terminal device with only one pn-junction. It is made up of n-type silicon wafer having two base…
