in the 1880s, 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 higher voltages was difficult; that is, the currents force couldnt be changed easily. transmitted at the low voltage needed for use in homes and businesses, it lost power after traveling only a mile. meanwhile, nikola tesla 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 loss. because of its advantages, ac triumphed by the end of the nineteenth century. what is the main, or central, idea of the passage? ac has distinct advantages over dc, so ac won the war of the currents. ac reverses direction and can be converted to lower or higher voltage.

Answer

Brief Explanations:

The passage first describes DC's drawbacks like difficulty in voltage - conversion and power - loss during transmission. Then it highlights AC's advantages such as easy voltage - conversion and efficient long - distance transmission. It concludes that AC triumphed due to its advantages. The first option encompasses the overall comparison and outcome, while the second option only lists some features of AC.

Answer:

AC has distinct advantages over DC, so AC won the War of the Currents.
