Amp up your understanding of electricity and magnetism with DOZENS OF DO-IT-YOURSELF EXPERIMENTS Electricity Experiments You Can Do At Home is a hands-on guide that helps you master the principles of electrical currents and magnetism. Each of the books three sections--direct current, alternating current, and magnetism--begins with step-by-step instructions for setting up your lab for the experiments that follow. Using inexpensive, easy-to-find parts, the experiments progress from basic to more complex and will spark ideas and encourage inventiveness. Expect unexpected results when you experiment with: * Diode-based voltage reducer * Compass-based galvanometer * Photovoltaic illuminometer * Utility bulb saver * Ripple filter * Xener-diode voltage regulator * AC spectrum monitor * Amperes law with wire loop * AC electromagnet * Handheld wind turbine * And dozens more projects ELECTRICITY EXPERIMENTS YOU CAN DO AT HOME helps you to: * Solve circuit problems in electricity * Build practical and interesting electrical and magnetic devices * Get ideas for science-fair projects * Prepare for advanced courses in electricity and electronics * Learn the basics of laboratory practice
