Question

Wired Faculty App

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

10 kΩ

20 kΩ

5 kΩ

2.5 kΩ

Solution

10 kΩ

Here: ΔV_c = 0.5 volt

ΔI_c=0.05 mA=0.05×10^-3

Output resistance is defined as the ratio of change in output voltage or collector voltage (V_CB) to the corresponding change in output current or collector current (I_C), with the input current or emitter current (I_E) kept at constant.

$Output resistance is given by R_{out} = \frac{∆ V_{c}}{∆ I_{c}} = \frac{0.5}{0.05 \times 10^{- 3}} = 10^{4} Ω = 10 kΩ$
