Pass Ratio : 100%
If the positive lead of a DMM, with the mode set to ohmmeter is connected to the base and the negative lead to the emitter and a high resistance reading is obtained, then what is the type of transistor that is being tested?
Explanation: If the positive lead of a DMM, with the mode set to ohmmeter is connected to the base and the negative lead to the emitter and a low resistance reading is obtained, then what is the type of transistor that is being tested is npn.

Pass Ratio : 100%
For the given transistor, what is the correct sequence of the pins from left to right?
Explanation: With the curved side facing us, the answer can either be collector-base-emistter, left to right, or emitter-base-collector. Hence the correct option is CBE, and that applies for an NPN transistor.
Question 10
Marks : +2 | -2
Pass Ratio : 100%
If the positive lead of a DMM, with the mode set to ohmmeter is connected to the base and the negative lead to the emitter and a low resistance reading is obtained, then what is the type of transistor that is being tested?
Explanation: There are multiple ways to test the BJT to be npn or pnp using a DMM based upon which terminals are connected to which lead of the DMM. If positive is to base and negative to the emitter of the BJT, and if a low reading is obtained and not a over limit, then the transistor is NPN.
