1.

In a common emitter amplifier, using output resistance of 5000 ohm and input resistance of 2000 ohm, if the input signal voltage is `10mV` and `beta = 50`, calculate output volatge & power gainA. `1.25V, 6250`B. `3V, 6250`C. `1.5V, 3050`D. None of these

Answer» Correct Answer - B
Voltage gain `= beta (R_("out"))/(R_("in"))`
power gain `= beta^(2) (R_("out"))/(R_("in"))`
