How do i test a transistor with a ohm meter using ohms?
By using ohms how can i tell which ones is the base,collector,emitter
by the ohms reading?
How can i tell if the transistor is NPN or PNP by ohms readings?
What should the base and collect ohms reading be?
What should the base and emitter ohms reading be?
What should the Collector and emitter ohms reading be?
Then if i switch the probe leads to change the reference it changes the ohms readings the other way

Testing a transistor with a Ohm meter does this tell us that the transistor is "conducting" because we are measuring each terminal in ohms instead of having a voltage drop across it ?
Some meters send out a voltage i think to the transitor to make sure the junctions have a .7 drop or so but measuring a transitor by ohms is that testing it if its conducting?
