The sine wave is a curved graph that shows electric cycles measured per second, called Hertz (Hz). DC stands for Direct Current. Unlike AC, it flows only in a certain direction and does not change ...

The coil of these generators rotates 50 times a second and that is why our mains supply is 50 Hz AC. The potential difference-time graph for an ... changes again. The DC supply and switch can ...

Electricity comes in two basic forms: Alternating Current (AC ... a generator in one box. You could spin the motor with 12V and have the generator produce a different voltage (even a DC voltage).

why do carmakers no longer use generators, which produce rich, creamery DC electricity? Why would it make any sense to generate AC, and then have to convert it to DC? As you probably guessed ...

set was little more than a motor connected to a generator. The motor might take, say, 12V DC and the output could be, for example 300V AC that would get rectified for the plate voltage in a tube ...
