Please tell me about CB mode is Ic/Ie & CC mode is Ic/Ib.

Why do we change modes from CC to CB or vice versa?
What is the practical application of changing transistor modes?

Ic/ie = Alpha.
Ic/ib = beta, b = a/(1-a).
A given = 0.99.
So b = 99 = 1+99 = 100.
Ic/ib = beta, b = a/(1-a).
A given = 0.99.
So b = 99 = 1+99 = 100.

Why are you adding 1 to 99?
