A Restarters' Training Session makes an easy introduction to the following sections down to and including Electronic Components. It consists of a presentation with audio commentary, lasting around 50 minutes.

• The water analogy - Understand electricity better by the analogy with a flow of water.
• Conductors and Insulators - The difference betwen them, and why you need to know.
• Electric circuits, volts amps watts and ohms - what every Restarter should know.
• Series and parallel circuits - Not quite sure of the difference? All is explained!
• AC and DC - what's the deal?
• Electronic components - recognition, failure modes and testing:
  • Basic electronic components - Resistors, capacitors, inductors and transformers, and quartz crystals.
  • Active components - Diodes and rectifiers, transistors, and integrated circuits (ICs).
  • Passive components - Switches, push-buttons and connectors.
  • Protection components - Various devices for over-voltage and over-current protection. Fuses are only the beginning!
• Batteries - different types, shapes and sizes, what they're good for, how to buy them, use them and dispose of them.
• Light bulbs - the several different types and their various shapes, sizes and bases, all explained.
• Electric motors - different types, how to recognise them, test them and maybe fix them.
• Power supplies - how they work, what can go wrong, and how to test and fix them.
• How radios work - basic theory to help you understand what might be wrong when you can't see it with your own eyes.
• Clocks - Basic Principles covers the principles of operation of both historical and modern clocks as background to repair.
• How flip clocks work - those cool retro clocks with split flip-down digits.
• All about SSDs - everything you always wanted to know but were afraid to ask.
