Could someone explain AC and DC generators?
If you take a regular horseshoe magnet and spin a coil of wire between (or past) the poles, then you generate a positive voltage as any part of the coil goes past one, and a negative voltage as it passes the other pole. If you want AC output to connect to anything else, then you use 2 slip rings on the axle that the coil is mounted on. The output waveform is a pure SINE wave. If you want DC output, then it gets a bit more complex, cos you want one connection to give a + output, and the other to give a – output To explain this, imagine your simple one coil device (multiple coils used in the real world) – there is just one slip ring, and it is cut in 2 places. one side of the coil connects to one segment, the other side of the coil to the other segment. This sort of slip ring is called a COMMUTATOR To pick up the DC voltage, there are 2 stationary carbon brushes (contacts) mounted at OPPOSITE sides of the circular commutator. When the coil spins, the connection between the coil and the b
