Web15 de mar. de 2008 · Transistor is a current amplifier. Therefore it's equivalent circuit represents a current amplifier at the output section. hoe is the conductance of the output. So 1/hoe is the resistance parallel to it. More the value of 1/hoe, better is the current source. So for a good transistor the value of hoe is very small.
