Δ I B =(30-20)=10 μ A Δ I C =(4.5-3) mA =1.5 mA β ac =(Δ I C /Δ I B )=(1.5 mA /10 μ A )=150 β ac =150

Q. The output characteristics of a transistor is shown in the figure. When $V_{CE}$ is $10 V$ and $1_{C} = 4.0 m A$ , then value of $β_{a c}$ is _______.

$Δ I_{B} = (30 - 20) = 10 μ A$
$Δ I_{C} = (4.5 - 3) m A = 1.5 m A$
$β_{a c} = \frac{Δ I _{C}}{Δ I _{B}} = \frac{1.5 m A}{10 μ A} = 150$
$β_{a c} = 150$
