Question

use the text to compare and contrast ac and dc. in the late 1880s, inventors nikola tesla and thomas edison were competing with each other. edison had developed direct current (dc), which is current that runs in a single direction. at that time, direct current was the standard form of electricity in the united states. tesla, however, had developed alternating current (ac), which reverses direction. as opposed to dc, which cannot be easily converted to lower or higher voltages, ac can be converted to different voltages with a transformer. edison didnt want to lose money on his dc patents, so he spread false information suggesting that ac was dangerous. over the years, though, ac won out as the method of choice. today, ac—not dc—provides the majority of our electricity. was developed by edison runs in a single direction can easily be converted to different voltages provides most electricity today

Explanation:

DC was developed by Edison, runs in a single - direction, and is hard to convert to different voltages. AC was developed by Tesla, can reverse direction, can be easily converted to different voltages with a transformer, and provides most of the electricity today.

Answer:

Was developed by Edison: AC: No, DC: Yes
Runs in a single direction: AC: No, DC: Yes
Can easily be converted to different voltages: AC: Yes, DC: No
Provides most electricity today: AC: Yes, DC: No
