I do not understand the equation for current gain:
Homework Equations
Ai = [itex]\alpha[/itex][itex]\frac{R4}{R4 + Ri}[/itex]
The Attempt at a Solution
I have pages of work on this, but basically what I know is [itex]\frac{Io}{Ie}[/itex] = [itex]\alpha[/itex]
then [itex]\frac{Ie}{Ii}[/itex] must equal [itex]\frac{R4}{R4 + Ri}[/itex], I don't see that.
