why in a transistor the emitter base junction act as low resistance while the base collector junction acts as high resistance?

Expert Answer:

The emitter base junction is forward biased, which means the electrons flow easily through the junction between the base and emitter, and hence it acts as a low resistance.
The collector-base junction is reverse biased, so the electrons do not flow easily, and hence it acts as a high resistance.
