Module 2 − Looking at Capacitors
Introduction
What you´ll learn in Module 2:
- In section 2.1 Capacitors.
- • Common capacitor types and their uses
- • Basic Circuit Symbols for Capacitors
- In section 2.2 Charge and Discharge
- • How capacitors work
- • What is charge?
- • Charge and discharge in a DC circuit
- In section 2.3 Capacitance
- • What is capacitance?
- • Dielectric.
- • Permitivity.
- • Dielectric strength and maximum working voltage.
- • Calculating the charge on a capacitor.
- In section 2.4 Capacitors in Circuits
- • Solving capacitor circuit calculations
- • Capacitors in series
- • Capacitors in parallel
- In section 2.5 Capacitor Quiz
Capacitors are one of the most useful components in electronics, and after resistors are the most numerous components in circuits. This module introduces diffent types of capacitor and describes their basic operation. Later modules look at how capacitors are used in AC circuits where, together with inductors, they perform an important job in many circuits.
This is module 2 of 14 modules.
Any module can be selected from the Home Page. In this module what you will learn is listed in the grey panel. It tells you "What you should know..." as a result of studying the complete module.
Each module is divided into several smaller sections and another "What you should know" panel explains what you will learn in that section section. Check your learning with the revision questions in each section, and the "Module Quiz" at the end of the module.
Study each section (numbered 2.1, 2.2 etc) in order and use the revision questions to help check your understanding.
