Lesson 5: Electronic and Electrical Components
Components come next, described in the terms of the electrical principles lesson.
What you will learn
- T6A Fixed and variable resistors; Capacitors; Inductors; Fuses; Switches; Batteries
- T6B Semiconductors: basic principles and applications of solid-state devices, diodes and transistors; Gain
- T6C Circuit diagrams: use of term schematic, basic structure; Schematic symbols of basic components
- T6D Component functions: rectifiers, relays, voltage regulators, meters, indicators, integrated circuits, transformers; Resonant circuit; Shielding
1. Read
- Electronics basics: Common componentsHelps with T6A, T6B, T6D
- Electronics basics: Capacitors, inductors and reactanceHelps with T6A
- Electronics basics: Schematic diagramsHelps with T6C
- All 46 T6 questions with their answers and explanationsEvery group, with the rule or source behind each answer
2. Explore
- Schematic symbols
Practice naming the symbols drawn in exam figures T-1, T-2 and T-3.
- Resistors and capacitors
Read the color bands of a resistor and convert them to ohms.
- Reactance and resonance
Pick an inductor and a capacitor and find the frequency where their reactances are equal. That is the resonant frequency of a tuned circuit made from the two.
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.
