This book contains graphs showing the properties of generators and motors, including the electrical output of two generators powered by hand, wind, and a 9 V battery. Additional graphs show the electromagnetic induction which produces or results from mechanical movement in common gadgets. Graphs also show the energy usage of light bulbs and common household appliances running on alternating current (AC), including responses to a dimmer switch. Solar power is briefly explored as an alternative energy. These data can be used for lesson plans by teachers and parents.
