Lesson 5: Circuit Components
Circuit components at this level are semiconductors, digital ICs, inductors, piezoelectric and optical devices.
What you will learn
- E6A Semiconductor materials and devices: semiconductor materials; bipolar junction transistors; operation and types of field-effect transistors
- E6B Diodes
- E6C Digital ICs: families of digital ICs; gates; programmable logic devices
- E6D Inductors and piezoelectricity: permeability, core material and configuration; transformers; piezoelectric devices
- E6E Semiconductor materials and packages for RF use
- E6F Electro-optical technology: photoconductivity; photovoltaic devices; optical sensors and encoders; optically isolated switching
1. Read
No guide covers this topic yet, so the explained questions are the reading for this lesson. Read each one and its explanation before you practice.
- All 68 E6 questions with their answers and explanationsEvery group, with the rule or source behind each answer
2. Explore
- Coil and toroid winder
Wind the same inductance on two different cores. Each core has its own AL value, so each needs a different number of turns.
3. Practice
Practice one group at a time. A group is ready when you have answered every one of its questions and learned at least 80 percent of them; a question counts as learned when your last three answers to it were correct. To review quickly, go through this lesson’s questions as flashcards.
