Answer» Answer: Resistance of base resistor is GIVEN as $R_b = 1.75 \times 10^4 ohm$ Explanation: As we know that voltage GAIN in COMMON EMITTER transistor is given as $\frac{v_{CE}}{v_{BE}} = \frac{i_c R_c}{i_b R_b}$ also we know that CURRENT gain in this transistor is given as $\beta = \frac{i_c}{i_b}$ $\beta = 50$ $\frac{v_{CE}}{v_{BE}} = \frac{3000}{R_b} \times 50$ $\frac{6}{0.7} = \frac{150000}{R_b}$ $R_b = 1.75 \times 10^4 ohm$ #Learn Topic : Transistor brainly.in/question/7698522
