Introductory Electronics

Contents / notes

• Distinction between metals, semiconductors and insulators; elementary knowledge of band gap is required.
• Intrinsic and extrinsic semiconductors, including n-type and p-type semiconductors.
• Uses of semiconductors and diodes in rectification and transistors in amplification.
• Elementary knowledge of diodes and transistors.

Candidate 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.
