00:00Question is, for a NPN transistor, the P-type crystal only acts as A collector only, B emitter
00:17only, C base only, D either emitter or collector.
00:26In NPN transistors, the emitter is N-type and base is P-type and collector is N-type.
00:46So, in NPN transistors, emitter and collector is N-type but base is P-type.
00:55So, the correct option will be C base only.
