n-p-n transistor has three leads A, B and C.
Connecting B and C by moist fingers, A to the
positive lead of an ammeter, and C to the
negative lead of the ammeter, one finds large
deflection. Then, A, B and C refer respectively
to :
(1) Emitter, base and collector
(2) Base, emitter and collector
(3) Base, collector and emitter
(4) Collector, emitter and base.
