If `alpha` and `beta` current gains in common-base and common-emitter configuration of a transistor, then `beta` is equal to

If alpha and beta are current gains in common base and common emitter configurations of a transistor, then beta is equal to

For a transistor x=(1)/(alpha)&y=(1)/(beta) where alpha & beta are current gains in common base and common emitter configuration. Then

Define current gain ratio (beta) in common emitter node.

If alpha and beta are the current gain in the CB and CE configurations respectively of the transistor circuit, then (beta-alpha)/(alphabeta)=
