The base of a transistor is of the order of
Correct answer: C. 10^-5 m
- A. 10^-2 m
- B. 10^-4 m
- C. 10^-5 m
- D. 10^-6 m
Explanation
The base region of a transistor is typically on the order of micrometers (10^−6 m) or sub-micrometers (10^−4 m). Transistor dimensions can vary based on the specific fabrication technology and requirements.Incorrect Options and Explanations: (a) 10^−2 m- This is too large for the dimensions of the base region in a transistor. (b) 10^−4 m- This is larger than typical transistor dimensions. (d) 10^−6 m - This is also a possible dimension for the base region of a transistor, but it's on the smaller end of the typical range.

About Electronics
A p-n junction forms when p-type and n-type semiconductor regions meet, creating a depletion layer, barrier potential and rectifying action. The work covers forward and reverse bias, junction current, diode characteristics, and how a diode converts alternating current into pulsating direct current through half-wave and full-wave rectification.
