How to select a transistor ??

Hello friends , in this video we will see the selection criterion for BJT, MOSFET and for IGBT.
This video also contains the answers of some questions like
1.What are the types of transistors ?
2.How does the BJT works ?
3.What is the difference betwwen NPN and PNP transistor ?
4.Which parameters are important to select a BJT ?
5.Why do we use MOSFET instead of JFET ?
6.What are the types of MOSFETs ?
7.what is the difference between Depletion mode & Enhancement mode MOSFET ?
8.Which parameters are important to select a MOSFET ?
9.Why there is a Body diode, in power MOSFETs ? etc..
