Narrative:

We were at 17;000 ft cruise altitude established on the X arrival into ZZZ; approximately 60 miles north of ZZZ VOR when we received a master caution on the cwp electric and looked up and saw the right generator light on. I identified and canceled the master caution and pulled out the non normal checklist. We checked to see if we had any cbs popped; but none had popped. The first officer was the pilot flying and I completed the non normal checklist for a generator failure. After 2 attempts at resetting the generator unsuccessfully; we completed the checklist and turned off the right generator. I explained to them what happened; told them which procedure we completed and agreed we would continue to ZZZ. A moment later; the flight attendant called me and said her work light in the galley had failed. I explained to her that we were having electrical problems and that we had to turn off the right generator. I told her we were landing in ZZZ and I would call her back. By the time all of these tasks were complete we were at 11;000 ft and being handed over to approach. I discussed with the first officer that the safest course of action would be to declare an emergency with ATC since we only had one generator left in the event the remaining generator failed. He agreed with me and I notified approach that we had a right dc generator failure and declared an emergency.
