A working transistor with its three legs marked P, Q and R is tested using a mustimeter. No conduction is found between P and Q. By connecting the common (negative) terminal of the mustimeter to R and the other (positive) terminal to P or Q, some resistance is seen on the mustimeter. Which of following is true for the transistor?
Text Solution
Verified by ExpertsD
Since no conduction is found when the multimeter is connected across P and Q it means either both P and Q are n -type or p -type. So, it means 
is base. When 
is connected to the common terminal and conduction is seen when another terminal is connected to 
and 
, so it means transistor is in 
configuration with R as the base.
