Introduction to Bipolar Junction Transistor in Hindi | Very Easy | Tech Gurukul by Dinesh Arya
A bipolar junction transistor (bipolar transistor or BJT) is a type of transistor that uses both electrons and holes as charge carriers.
Unipolar transistors, such as field-effect transistors, only use one kind of charge carrier. BJTs use two junctions between two semiconductor types, n-type and p-type.
BJTs are manufactured in two types: NPN and PNP

Draw acircuit using BJT for switching of a DC load. Load comprises of 5kW at a voltage of 200V DC. Represent the load with a resistance. Available stock of BJTs have βDC of 100, 120 and 150. Switching should be performed using a 12V battery

In saturation mode there will be large currents due to F.B -F.B and it will be close switch
In cut-off mode there will be zero current due to R.B -R.B and it will be open switch
