Consider the transistor shown in the figure. Its terminals are marked as 1, 2 and 3. Usingmultimeter a student tries to identify the base of transistor, he proceeds as follows.
Experiment I: He touches the common lead of the multimeter to 2, then on touching otherlead of multimeter to 1, he has not get any beep (indication of conduction) but whenconnected to 3, he gets a beep.
Experiment II: He connects the common lead of multimeter to 1 and other lead to 2 and 3,turn by turn and then he gets a beep of both the connections.From this we conclude that …..
