Consider the transistor shown in figure, its terminals are marked as 1,2 and 3. Using multimeter one try to identify the base of transistor, he proceed in the way as follows. Experiment I: He touches the common lead of the multimeter to 2, then on touching other lead of multimeter to 1 he hasn.t got any beep (indication of conduction) but when connected to 3 got the beep.
Experiment II: He connected the common lead of multimeter to 1 and other lead to 2 and 3 one by one then in this case he got beep for both connections. From this we conclude that

A

1 is base
