Direct Current Alternating Current

In this amazing story of high stakes competition between two titans, Richard Moran shows how the electric chair developed not out of the desire to be more humane but through an effort by one nineteenth-century electric company to discredit the other. In 1882, Thomas Edison ushered in the "age of electricity" when he illuminated Manhattan's Pearl Street with his direct current (DC) system. Six years later, George Westinghouse lit up Buffalo with his less expensive alternating current (AC). The two men quickly became locked in a fierce rivalry, made all the more complicated by a novel new application for their product: the electric chair. When Edison set out to persuade the state of New York to use Westinghouse's current to execute condemned criminals, Westinghouse fought back in court, attempting to stop the first electrocution and keep AC from becoming the "executioner's current." In this meticulously researched account of the ensuing legal battle and the horribly botched first execution, Moran raises disturbing questions not only about electrocution, but about about our society's tendency to rely on new technologies to answer moral questions.

For RVers who remain mystified by their RV's electrical systems--120-volt alternating current (AC) and 12-volt direct current (DC)--this book is a godsend. It provides a better understanding of what electricity is and what it does. This problem-solving reference answers questions such as: "Why do interior lights dim or burn out rapidly?" and, "Why won't the batteries recharge after a night without electricity?" It tells you how to repair and improve electrical systems; how to troubleshoot faulty brakes, taillights, and "house" circuits; how to detect dangerous shorts, faulty grounds, inadequate connections, malfunctioning switches, dead battery cells, or current leakage; and much more. This book could save your vacation, or even your life. All you need to know about RV electricity, including: How to safely use a campground hookup.How to increase battery charging efficiency.How to take the pulse of your AC and DC electrical systems.How to recognize and correct dangerous wiring practices.How to troubleshoot electrical problems of all types.How to upgrade your RV from fuses to circuit breakers.How to calculate your electrical needs and upgrade your system to meet them.How to select the most effective components--batteries, alternator, regulator, coverter, charger, generator, solar panels.How to recognize phantom electrical loads that can drain your batteries.

Direct current - Direct current (DC or "continuous current") is the constant flow of electric charge from high to low potential. This is typically in a conductor such as a wire, but can also be through semiconductors, insulators, or even through a vacuum as in electron or ion beams. In direct current, the electric charges flow in the same direction, distinguishing it from alternating current (AC). A term formerly used for direct current was Galvanic current. [of direct current]

High-voltage direct current - HVDC or high-voltage, direct current electric power transmission systems contrast with the more common alternating-current systems as a means for the bulk transmission of electrical power. The modern form of HVDC transmission uses technology developed extensively in the 1930s in Sweden at ASEA.

Alternating current - An alternating current (AC) is an electrical current where the magnitude and direction of the current varies cyclically, as opposed to direct current, where the direction of the current stays constant. The usual waveform of an AC power circuit is a sine wave, as this results in the most efficient transmission of energy.

Neutral direct-current telegraph system - In telecommunication, a neutral direct-current telegraph system (single-current system, single-current transmission system, single-More system) is a telegraph system in which (a) current flows during marking intervals and no current flows during spacing intervals for the transmission of signals over a line, and (b) the direction of current flow is immaterial.
