Question

Study the schematic carefully. a schematic symbol. a straight line is labeled base. a line extending up and to the right is labeled collector. a line extending down and to the right with an arrow pointing away from the base is labeled emitter. what does this schematic represent?

1) a capacitor
2) pnp transistor
3) a resistor
4) an npn transistor

Answer 1

The schematic represents an NPN transistor, a device that uses base voltage to control current flow between emitter and collector.

Step-by-step explanation:

The schematic described is a representation of a transistor, specifically an NPN transistor. It is a semiconductor device used to amplify or switch electronic signals and electrical power. The base, collector, and emitter are the three terminals of the transistor. When a voltage is applied to the base, it acts as a control valve allowing current to flow from the emitter to the collector. This is how it functions in a circuit, using base voltage to regulate the collector current.
