A) Negative charge moves from collector to base
B) Negative charge moves from emitter to base
C) Holes move from base to collector
D) Holes move from emitter to base
Correct Answer: B
Solution :
Key Idea: Direction of current is taken opposite to direction of motion of electrons. A bipolar junction transistor consists of three regions of doped semiconductors. A small current in the center or base region can be used to control a larger current flowing between the end regions (emitter and collector) Since direction of current is from base to emitter, the negative changes move from emitter to baseYou need to login to perform this action.
