Question

1. Describe the basic principle of operation of a bipolar junction transistor including

explanation for the following:
a. why majority carriers crossing into the base from the emitter pass to the collector
b. why the collector current is almost unaffected by the collector potential​

Answer 1

Bipolar junction transistor or simply transistor is the same. Two types of charges the hole or the electron makes it bipolar. ... The emitter-base junction junction is forward biased to make emitter emit electrons. And base-collector region is reverse biased to collect electron by the collector.
