Question

Difficulty: MediumTransistors

In standard electronic schematic symbols for bipolar junction transistors (BJTs), the arrow is located on the emitter terminal and points outward away from the base for an NPN transistor, indicating the direction of conventional current flow.

Answer: Answer

Answer

True
The statement is true because electronic schematic standards place the directional arrow exclusively on the emitter lead. For an NPN transistor, this arrow points outward (away from the base), which reflects the direction of conventional current flow across the forward-biased base-emitter junction.

Step-by-Step Solution

1
Identify the specific terminal that carries the directional arrow on a BJT schematic symbol.
The arrow is always placed on the emitter terminal, distinguishing it from the collector and base leads.
Standard electronic schematic conventions designate the emitter lead with an arrow to define transistor polarity and terminal identity.
2
Determine the orientation of the arrow for an NPN transistor configuration.
In an NPN transistor, the arrow points outward, away from the base.
The arrow represents the direction of forward-biased conventional current flow, moving from the P-type base material out through the N-type emitter material.
3
Evaluate the accuracy of the full statement.
The statement correctly identifies both the terminal location (emitter) and the outward direction for an NPN transistor.
Both structural elements conform exactly to standard electrical schematic rules.
