Choose the corrector relation between the transistor parameters `alpha` and `beta`.

Options

A. `beta = (1 - alpha)/(alpha)`
B. `beta = (alpha)/(1 - alpha)`
C. `alpha = (beta - 1)/(beta)`
D. `alpha beta = 1`

Answer

B

Explanation

From one side, `(t - x)/(5) = 1.5`
From other side, `(x)/(2) = 1.5 to x = 3`
`:. (t - 3)/(5) = 1.5 implies t = 7.5 + 3 = 10.05 cm`
