In a transistor
Correct answer: B. length of collector is greater than that of emitter
- A. length of emitter is greater than that of collector
- B. length of collector is greater than that of emitter
- C. both collector and emitter have the same length
- D. none of these
Explanation
In a transistor, the collector is typically larger in size compared to the emitter. This design allows for better heat dissipation and enhances the transistor's overall performance.Incorrect Options and Explanations: (a) length of emitter is greater than that of collector - This is not a typical configuration in transistors. (c) both collector and emitter have the same length - Generally, the collector and emitter have different lengths for optimal transistor performance. (d) none of these - The length of the collector and emitter is a consideration in transistor design.

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.
