... answer to (a), since the inductor essentially acts as a short across the 1000 resistor after the switch S has been in position A for a long time. After the switch is thrown to position B, the circuit will be as shown to the right. The initial current through the 100 and 500 resistors will remain ...

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.
