RE: Discharge resister in Generator
If it is Lightning Discharge, the resistors are always non-linear - resistance of the resistor stack falling rapidly once the rated voltage threshold is crossed.

RE: Discharge resister in Generator
For the brushless excitation, the resistor is typically the same kind as that used to prevent condensation in air handling environments. The device is typically not finned (although it could be) and is a circuit comprised of several "strip" or "tube" type resistive elements connected in some series/parallel combination.

Discharge resistor in generator field circuit is cut in whenever Field Contactor is open.
This is to short circuit the Generator field winding so that the stored energy in the field windings is quickly discharged.
