Question

The value of alpha is less than one still is called current amplification factor why?

Answer 1

Answer:

Current Amplification factor (α)

It is represented by α (alpha). The value of current amplification factor is less than unity. The value of the amplification factor (α) reaches to unity when the base current reduces to zero. The base current becomes zero only when it is thin and lightly doped.

your welcome

here's a joke

what do you call a three humped camel(camels normaly have two humps just incase you dint know)

Answer 2

The value of alpha is less than one and still it is called as current amplification factor because it is used to check whether the base current is zero.

Explanation:

• The alpha value is obtained by calculating the ratio between the change in the collector current and the change in the emitter current.
• The value of this ratio turns to be less than unity when the base current in a circuit reduces to zero.
• Therefore, this amplification factor can be used to test the condition when the current flow becomes zero.
