hi, I'm currently learning about self-excited and separate shunt generators, and I'm having a hard time comprehending the residual magnetism. i was just wondering if a generator have lost all of its residual magnetism, can it still build up an output voltage? can someone explain this to...

A galvonometer has a coil resitance of 460 ohms and a full scale deflection current of of 100^10*-6 A What shunt resistor is needed to convert this galv.. into an ammeter which has a full scale deflection current of 200 ^10*-3 A? What is the resitance of the ammeter when it is completed? What...
