- Collector.
- Emitter.
Why the elections should leave the emitter?
What polarity do interpoles take in a DC generator?
- The same as the next main pole behind in the direction of rotation.
- Either, providing they lay on M.N.A.
- The same as the next main pole ahead in the direction of rotation.
Help!? I thought Interpoles in a generator are same polarity as main pole ahead of it? Behind for motors?
