Correct Option - 3

Detailed Solution:

$i_{b} = \frac{5 - 0.7}{8.6} = 0.5 m A$

$\Rightarrow I_{c} = β I_{b} = 100 \times 0.5 m A$

By using

$V_{C E} = V_{C C} - I_{C} R_{L} = 18 - 50 \times 1 0^{- 3} \times 100 = 13 V$

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

Raj Pandey

Here $Δ V_{c} = 0.5 V, Δ i_{c} = 0.05 m A = 0.05 \times 1 0^{- 3} A$

Output resistance is given by

$R_{o u t} = \frac{Δ V_{c}}{Δ i_{c}} = \frac{0.5}{0.5 \times 1 0^{- 3}} = 1 0^{4} Ω = 10 k Ω .$

An npn transistor operates as a common emitter amplifier with a power gain of 10?. The input circuit resistance is 100Ω and the output load resistance is 10kΩ. The common emitter current gain 'β' will be -----------. (Round off to the Nearest Integer)

Raj Pandey

Power gain = (i_c² R_c) / (i_b² R_B) = (i_c/i_b)² (R_c/R_B) = (10²)² (10? /10³) = 10?
i_c/i_b = 100 ⇒ β = i_c/i_b = 100
