Bipolar junction transistor
A bipolar junction transistor (bipolar transistor or BJT) is a type of transistor that uses both electron and hole charge carriers. In contrast, unipolar transistors, such as field-effect transistors, only use one kind of charge carrier. For their operation, BJTs use two junctions between two semiconductor types, n-type and p-type.enpediatransistor on the left. PNP transistors have emitter (e),base (c) and collector (c) terminals just like NPN transistors.

So, again, transistors are used when we want electrical current to control the state of switches in a circuit. When the PIR sensor detects no motion, it outputs no current, so the transistor does not turn on. When the transistor does not receive sufficient current at its base, no current can flow from emitter to collector to power the load, which in this case is a motor.How to Connect a Transistor as a Switch in a CircuitSee all results for this questionWhat are the advantages of Transistor Transistor Logic?What are the advantages of Transistor Transistor Logic?hobbyprojects There are more disadvantages than advantages, as TTL refers to a legacy term regarding switching logic. These were some of the very first integrated circuits, which would perform very basic functions, such as logic 'and', 'or', 'exclusive or', but also the complete 'not and' and others.What are the advantages of TTL (transistor transistor logic)?See all results for this questionWhat is the significance of arrow symbol in transistor?What is the significance of arrow symbol in transistor?The arrow in transistor symbol represents the direction of conventional emitter current flow and thereby defines the direction of other currents in the transistor.What is the significance of arrow in the transistor symbolSee all results for this questionWhy is a transistor called a transistor?Why is a transistor called a transistor?Transistor is a device which offers resistance when connected across the circuit. Hence it is called a resistor. Also that it amplifies the input signal and transfers it to the output part of the amplifier. Hence called by the name of trans resistor and thus transistor.Why are transistors called transistors? - QuoraSee all results for this question
