Introductory electronics: JAMB Physics Past Questions and Answers
What the JAMB syllabus covers in Introductory electronics
Our summary: Why metals, semiconductors and insulators differ, and how diodes and transistors are used.
- Distinction between metals, semiconductors and insulators (Elementary knowledge of band gap is required.)
- Intrinsic and extrinsic semiconductors (n-type and p-type semiconductors)
- Uses of semiconductors and diodes in rectification and transistors in amplification
- Elementary knowledge of diodes and transistors
Objectives
- differentiate between conductors, semiconductors and insulators;
- distinguish between intrinsic and extrinsic semiconductors;
- distinguish between electron and hole carriers;
- analyse diodes and transistors;
- relate diodes to rectification and transistors to amplification.
