Find the curernt gain in a common base ...

Find the curernt gain in a common base circuit if the base curent is 50 `muA` emitter current is 1.2 mA

Text Solution

Verified by Experts

`alpha= (I_(c ))/( I_(e )) rArr I_(e) = 1.2 mA`
`i_(c ) = I_(e ) - I_(b) = 1.15 mA`
`alpha= (I_(c))/( I_(e)) = (1.15) /(1.2) = 0.958`
