Question

Accepted Answer

PNP transistor is a type of bipolar junction transistor. Multimeter is used to measure voltage, current and resistance. Tracing a circuit involves identifying the path of current flow. Mounting and unmounting components on PCB involves soldering and desoldering.

PNP transistor is a three-layer semiconductor device with emitter, base and collector regions.
Multimeter can be used in different modes such as voltage, current and resistance mode.
To trace a circuit, start from the power source and follow the path of current flow.
Mounting and unmounting components on PCB involves soldering and desoldering using a soldering iron.
It is important to follow proper safety precautions while working with electronic components.
