On a standard electronic schematic diagram, the arrow on the emitter terminal of an NPN bipolar junction transistor points outward, away from the base.

Cevap: Cevap

Cevap

True: The emitter arrow on an NPN transistor schematic symbol points outward, away from the base.
In standard schematic diagrams, all bipolar junction transistors place a directional arrow on the emitter lead. For an NPN transistor, this arrow points outward, away from the base terminal, representing conventional current leaving the device. A widely used technician mnemonic is 'NPN = Not Pointing iN'.

Adım Adım Çözüm

1
Identify the component type and schematic lead conventions.
The component is an NPN bipolar junction transistor (BJT) consisting of Base, Collector, and Emitter leads.
Determining the transistor family and terminal configuration is required to verify the symbol markings.
2
Determine the arrow placement and orientation for the NPN configuration.
The arrow is always positioned on the emitter lead and points outward (away from the base line).
Schematic symbols use the emitter arrow to indicate the direction of conventional current flow, which flows out of the emitter in an NPN transistor (commonly recalled with the mnemonic 'Not Pointing iN').
3
Evaluate the accuracy of the provided statement.
The statement matches standard schematic conventions exactly.
An outward-pointing emitter arrow uniquely defines the NPN transistor symbol.
