... 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.
