20. In an NPN transistor, the arrow is pointed towards
(A) the collector
(B) the base
(C) depends on the configuration
(D) the emitter​

Answer 1

Answer:

the arrow pointing towards the emmiter

Answer 2

Answer:

The right option is (D) - the emitter.

Explanation:

• The NPN transistor is made by putting the p-type semiconductor in between two N-type semiconductors.
• It's the most commonly used BJT i.e, bipolar junction transistor.
• NPN transistor has three terminals namely, emitter, base, collector.
• The Emitter is responsible for supplying the charge carriers to the collector.
• While the collector is responsible for collecting most of the charges and the base helps in triggering and controlling the amount of current flow from the emitter to the collector

Therefore, the arrowhead in the NPN junction transistor is pointed toward the Emitter to indicate the direction of the flowing current from emitter to collector.
