Description : What is the difference between BJT and FET?

Answer : BJT  is  a  current  opperated   transistor  while  FET   is  a  field   opperated  transistor.

Description : What is the value of Beta in power BJT?

Answer : The beta value in power BJT is 5 to 10.

Answer : Beta is the current gain which is the ratio of collector current to base current.

Description : What is the difference between forward and reverse bias?

Answer : Forward bias is a PN junction bias which allows current to flow through the junction. Forward bias decreases the resistance of the depletion layer. Reverse bias is a PN junction bias that allows only ... Positive polarity on the n-type material and negative polarity to the p-type material.

Description : Differentiate between Natural and Forced commutation

Answer : Natural commutation Forced commutation Source is AC Source is DC External commutating componants are not required  External commutating componants are required SCR turns off ... in controlled rectifiers, AC voltage controllers etc.  Used in choppers & inverters etc
