collector current. (At least not without some unwanted side e ff ects.) Third, also unlike a
resistor, a BJT is not a linear device. Meaning that a change in collector voltage will not
a
ff ect the collector current. And fourth, the collector current is a ff ected by the transistor’s
temperature! The more it heats up, the more current will flow.
Now, for the PNP transistor, all of the above applies, too – except for two little details.
Unlike with the NPN,
the PNP transistor decreases its collector current when the
voltage at its base increases . So you have to bring the base voltage below the emitter 30
to open the transistor up. Also, that collector current flows out of, not into the collector!
Again, the voltage is measured between base and emitter. 30
