In the $CB$ mode of a transistor, when the collector voltage is changed by 0.5 volt, the collector current changes by 0.05 mA . The output resistance will be

Options:

Answer:

Solution:

Here: $Δ V_{c} = 0.5 volt, Δ I_{c} = 0.05 mA = 0.05 \times 1 0^{- 3} A$ Output resistance is given by $R_{out} = \frac{Δ V _{c}}{Δ I _{c}} = \frac{0.5}{0.05 \times 1 0 ^{- 3}} = 1 0^{4} Ω = 10 K Ω$
