Hydro-electric generators typically exhibit better governor response
than thermal generators because: A. Hydro-electric generators
typically have more stored energy B. Thermal generators typically do
not carry spinning reserve C. Water is a better conductor than steam D.
Hydro-electric generators utilize microprocessor based governors
while thermal units utilize mechanical governors
