Question

In the case of constants ‘α’ and ‘β’ of a transistor ______.

Options

• α = β

• β < 1, α > 1

• α = β²

• β > 1, α < 1

Answer 1

In the case of constants ‘α’ and ‘β’ of a transistor β > 1, α < 1.

Explanation:

For a transistor,

α = `I_C/I_E`

β = `I_C/I_B`

Since I_E = I_C + I_B​, we get α < 1 and β > 1.
