Question

In a transistor in CE configuration, the ratio of power gain to voltage gain is ____________.

विकल्प

• `alpha`

• `beta//alpha`

• `betaalpha`

• `beta`

Answer 1

In a transistor in CE configuration, the ratio of power gain to voltage gain is `beta`.

Explanation:

For CE configuration, voltage gain `= beta xx "R"_"L"//"R"_"i"`

`"Power gain" = beta^2 xx "R"_"L" // "R"_"i" Rightarrow "Power gain"/"Voltage gain" = beta`
