34-3 Voltage Sources 34-4 Electric Resistance 34

... The amount of charge that flows in a circuit depends on the voltage that comes from the source – it also depends on the resistance that the conductor offers. o The resistance that the conductor gives to the flow of charge is called the electrical resistance. This resistance depends on a few things: ...

Metadyne



A metadyne is a direct current electrical machine with two pairs of brushes. It can be used as an amplifier or rotary transformer. It is similar to a third brush dynamo but has additional regulator or ""variator"" windings. It is also similar to an amplidyne except that the latter has a compensating winding which fully counteracts the effect of the flux produced by the load current. The technical description is ""a cross-field direct current machine designed to utilize armature reaction"". A metadyne can convert a constant-voltage input into a constant-current, variable-voltage output.
