A working transistor with its three legs marked P, Q and R is tested using a multimeter. No conduction is found between P and Q. By connecting the common (negative) terminal of the multimeter to R and the other (positive) terminal to P or Q, some resistance is seen on the multimeter. Which of the following is true for the transistor?
1. It is a pnp transistor with R as emitter
2. It is an npn transistor with R as collector
3. It is an npn transistor with R as base
4. It is a pnp transistor with R as collector

its 3
as base region is doped maximum so there will be some resistance
while emiter is doped minimum
right??????????
