supply electricity to cities in the late 1880s is often called the ’War of Currents ’‚ as this battle ultimately decided which type of current became the standard for the generation of electricity today. Due to different advantages and disadvantages‚ Edison promoted direct current (DC) for electric power distribution‚ whereas Westinghouse and Nikola Tesla both advocated alternating current (AC). Edison ’s direct current was initially the standard for the United States for electricity distribution

for some of the modern conveniences of today‚ Thomas Edison and Nikola Tesla. Edison perfected the incandescent light bulbs and devised a system of electrical current for homes and businesses. Tesla’s biggest innovation was introducing alternating current as the standard for modern electric power‚ breaking Edison’s monopoly on direct current power. Inventors Thomas Edison and Nikola Tesla were opposite sides of the same coin. Edison‚ a brilliant business man with no formal education and Tesla‚

Current Situation The image of professional baseball has‚ by and large‚ been an idyllic and relatively unblemished one from its roots as the national pastime in the mid-1800s until the latter part of the 20th century.
