Some of the questions that I could remember are:
1. Fly back time is associated with ___ (CRO)
2. I/P impedence of Opam is ____ (high)
3. ohmic contact helps to drive ____ (MOSFET)

Q: Why is MOSFET preferred than BJT in power systems?
Q: Diff between Class A & class B amplifier.
Q: Why is Push pull arrangement used?
Q: What will happen if the load of an Half wave rectifier is replaced by capacitor. Draw The wave form.
All you have to do is to boost up electronics to the fullest that is enough.
