the arrow on emitter of a transistor indicates?
Answers
Answer:
Before going to read the answer; know this fact that in electronics conventional current always flows from p-type material to n-type material.
The npn and pnp transistors stands for as follows-
NPN- it has n-type semiconductor material used as emitter , p-type semiconductor material used for base and n-type for the collector region with varying doping concentrations . The figure below shows the symbol of npn transistors. The arrow mark in the emitter side shows the direction of conventional current flow will be from base to emitter(i.e from n-type (emitter) to p-type(base).
NPN PNP
PNP-it has p-type semiconductor material used as emitter , n-type semiconductor material used for base and p-type for the collector region with varying doping concentrations. The figure above showing the arrow simply denotes that conventional current flows from emitter to base (i.e from p-type (emitter) to n-type(base) in pnp transistor.
I hope you got your concept clear on this basic doubt from electronics.
Answer:
The arrow on the symbol for bipolar transistors indicates the PN junction between base and emitter and points in the direction in which conventional current travels.
