A working transistor with its 3 lega marked P,Q,R is tested using a multimeter..no conduction is found bw P and Q.By conncetng common -ve terminal of multimeter to R and other +ve terminal to P or Q,some resistance is seen..the transistor is (AIEEE 2008)1.npn-R collector2.npn-R base3.pnp-R collecot4.pnp-R emitter...pls give the concept of it....
