Batteries‚ Resistance and Current “Battery-Resistor”: Check “show battery” and “show cores”‚ watch what happens‚ adjust some variables 1. Why do electrons (blue dots) move? Draw a diagram of the battery‚ label the flow of electrons. The flow of current (+) is opposite; draw this and note if toward or away from + terminal of the battery. The electrons move because of the battery voltage. The current flows in the opposing direction of the electrons and the electrons flow towards the positive

non-technological factor to shape electricity was the business- and competition-fueled "War of Currents" of the late 19th century between alternating and direct current AC and DC‚ respectively ("Electricity‚" 2006). During the initial years of electricity distribution‚ Thomas Edison ’s direct current was the standard for the United States‚ and Edison was not disposed to lose all his patent royalties. Direct current worked well for the incandescent lamps that were the principal load of the day. However

Magnetic effect of electric current is one of the major effects of electric current in use‚ without the applications of which we cannot have motors in the existing world. A current carrying conductor creates a magnetic field around it‚ which can be comprehended by using magnetic lines of force or magnetic field lines. The nature of the magnetic field lines around a straight current carrying conductor is concentric circles with centre at the axis of the conductor. The direction of the magnetic field

THE WAR OF CURRENTS Tesla vs Edison: THE WAR OF CURRENTS In the "War of Currents" era (sometimes "War of the Currents" or "Battle of Currents") in the late 1880s‚ George Westinghouse and Thomas Edison became adversaries due to Edison’s promotion of direct current (DC) for electric power distribution over alternating current (AC) advocated by Westinghouse and Nikola Tesla.

After opening the first commercial power plant‚ Edison was only able to distribute electricity to one square mile of Manhattan and so it was found that using direct current (DC) was not an ideal way to get electricity distributed across long distances. Around that same time‚ Nikola Tesla was diligently trying to master the alternate current (AC) motors and generators even though he was discouraged from doing so. After proving his invention to be a practical solution for this problem‚ George Westinghouse
