Dear Student,

Important Topics of semiconductor and electronics :-

Energy band diagram.
Differences between:

Intrinsic semiconductor and extrisinic semiconductor.

N type and p type semiconductor.

Digital and analogue signal.

Logic gates.
Forward biased and reversed biased characteristic curve.
Zener voltage.
Diagram of half wave and full wave rectifier with their input and output signals.
Transistor as an amplifier.
Transistor as an oscillator.

For a quick revision, it will be best if you solve past year papers and latest sample papers. You can also go for revision of short and crisp notes made by you or from any other coaching institute. Do not forget to revise all the formulas and equations.

Happy Learning!
