Electricity and Electronics

This project-book contains 46 projects that explore electromagnetic forces, static electricity, current flow, motors, resistance and capacitance, generating electricity, solid state electronics and radio frequency energy. It discusses how to detect an approaching thunderstorm, build a generator, harness the power in a potato and keep insects away with sound waves. The materials needed for the projects should be easily available, and the experiments have been designed with safety in mind, all working with low voltage (a six-volt battery) rather than mains electricity.
