Answer» Correct option: (1) a low resistance Explanation: When the negative probe of a multimeter (adjusted to work as an ohm meter) is placed on the base of a p–n–p transistor, and the other probe is placed on the of the other pins, it will show a ‘low resistance’ reading. This is so because this way, of connecting the multimeter probes, corresponds to a forward biasing of the (p–n junction) being investigated. |
