In a schematic, if the arrow on the emitter is pointing out, what type of transistor is represented?

In a schematic, when the arrow on the emitter points outward from the body of the transistor, it indicates that the transistor is a PNP type. The direction of the arrow is essential because it reflects the current flow and the type of charge carrier.

In a PNP transistor, the majority carriers are holes, and conventional current flows from the emitter to the collector. This outward arrow signifies that current flows out of the emitter region. Conversely, in an NPN transistor, the arrow points in toward the emitter, indicating that electrons, which are the majority carriers in this type, flow into the emitter.

Recognizing the significance of the arrow direction helps in understanding the operation of different types of transistors in circuit applications. In the context of this question, the identification of the emitter's arrow direction leads to the correct classification of the transistor as a PNP type.
