Question

A current ratio of ic/ie is usually less than one and is called: select one:

a. alpha

b. beta

c. omega

d. theta

Answer 1

Answer:

A current ratio is usually less than one.

Explanation:

As we know that Emitter current in common emitter configuration is written as;

$I_{e}=I_{c}+I_{b}$

and the ratio of $\frac{I_{c} }{I_{e} }$  is less than one is called as alpha.

Option a) is correct.

Answer 2

Answer:

a. alpha

A current ratio of ic/ie is usually less than one and is called: alpha.

Explanation:

Because it is the ratio of collector current to emitter current and true collector current is less than emitted, it is referred to as alpha or current gain. As a result, the collector current is less than the emitter current, and the ratio is less than one. β = Ic/Ib. α = Ic/Ie. γ =Ie/Ib. The ratio of collector current to emitter current is defined as alpha (αdc). The current gain is defined as the ratio of collector current to base current in beta (βdc).
