∵ β AC =((Δ IC/Δ IB)) VC E ⇒ β DC =(IC/IB) Ratio =β AC: β DC =150: 150=1: 1

Q.
The output characteristics of a typical $n - p - n$ transistor in $CE$ configuration are shown. When $V_{CE} = 10 V$ and $I_{C} = 4.0 m A$ , then ratio of $β_{A C}$ and $β_{D C}$ is

$∵ β_{A C} = (\frac{Δ I _{C}}{Δ I _{B}}) V_{CE}$
$\Rightarrow β_{D C} = \frac{I _{C}}{I _{B}}$
Ratio $= β_{A C} : β_{D C} = 150 : 150 = 1 : 1$
