But the question is that they ask that if p terminal of supply is connected with p terminal of npn transistor what should be the reading of ohm meter with other two terminals not only for emitter terminal.

When NPN base is conected to P-terminal or P-probe, the transister will operate under forward bias. In forward bias the deplition layer decreases. Then more number of electrons & holes will move from one region to the other region. Hence the resistance becomes low.

In npn base is p juction and when postive prop is coonected to pterminal then it become forward bias and as we know in forward bias resistance is very low.

As the transistor becomes forward biased, it offers low resistance.

In NPN transistor, base terminal is of p-type. So, when the probe positive terminal is kept on ptype of transitor, now it is just like a transistor in forward bias, which offers a low resistance.

Since base emitter is forward biased so answer is low resistance.

But, There is closed path. So, what difference does it make, positive/negative. So, I think open is the answer
