For a transistor `1/alpha -1/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

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 current gains in common-base and common-emitter configuration 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

If alpha" and "beta are the roots of the equation x^(2)+3x-4=0 , then (1)/(alpha)+(1)/(beta) is equal to

For a transistor , beta = 100 . The value of alpha is
