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

Thanks for the answer @Ajay.

Why do we change modes from CC to CB or vice versa?

What is the practical application of changing transistor modes?

Γ=1÷(1-α).

The explanation is super, Thanks @Ajay.

Ic/ie = Alpha.

Ic/ib = beta, b = a/(1-a).

A given = 0.99.

So b = 99 = 1+99 = 100.

Please explain about CB and CC.

Why are you adding 1 to 99?
