Experiment no.6 ( transistor check )

Using a multi-meter, set to diode test, ( as transistors are made using at least two diodes)

We can work out the PNP and NPN type, and determining the collector, base and emiter, we find the voltage across the three listed above .

NOTE:

Positive leads on the base indicate that it is a p type transistor, negative leads on the base indicate that the transistor is N type . When taking the reading the lowest reading is normally the collector and the highest reading the emitter.
