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).

increasing the rate of rotation increasing the strength of the magnetic field increasing the number of turns on the coil The diagram shows four different positions of the coil in a dynamo ...

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 ...

Jeff suggests that you could replace the function generator with just a manual AC source by switching the leads on a battery back and forth. Some people call these AC to DC converters "wall warts ...

Here's what you should know about AC- and DC-coupling. When we think about solar panels and batteries, we don't really give much thought to all the wiring and other little boxes on the wall.
