Question
AC vs. DC
In the 1800s, the War of the currents began, Thomas Edison developed direct current, or DC a type of electricity that flows in one direction by 1887, DC was in use around the United States. It had some drawbacks, though. Converting it to lower or hgher voltages was difficult; that is the current's force couldn't be changed easily. Transmitted at the low voltage needed for use in homes and businesses, it lost power after travelling only a mile. Meanwhile, Nikola Telsa was working with alternating current, or AC. AC reverses direction many times per second and can be changed to different voltages. At high voltage, it can be transmitted efficiently, traveling hundreds of miles with little energy lost. Because of its advantages, AC triumphed by the end of the nineteenth century.
Responses:
AC reverses direction and can be converted to lower or highway voltage
AC has distinct advantages over DC, so AC won the War of the Currents
Thomas Edison and Nikola Telsa were competitors
By the late 1800s DC was used in the United States
