With Basic Electricity, Second Edition, you can teach yourself all about electricity—for everyday understanding or as a basis for further study. This easy-to-use guide takes you through the basics of electricity and familiarizes you with the workings of voltage, current, resistance, power, and other circuit values in direct-current and alternating-current electricity.

Through step-by-step problem-solving, you’ll gain a true understanding of the basic rules, laws, concepts and equations of electric circuits.
