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 1: He touches the common lead of the mulimeter to 2 then on touching other lead of miltimeter of 1 he hasn't got any becp(indication of conduction)but when connected to 3got the beep Experiment II : He connects the common lead of multimeter to 1 and other lead to 2 and 3 turn by turn then in this case he got beep for both connections. From this we conclude that
