Question 1
What is the formula for voltage gain (A) in a common emitter amplifier?
- A = g_m * R_C
- A = -g_m * R_C / (1 + g_m * R_E)
- A = R_C / R_E
💡 Hint: Remember the role of resistors in amplifying signals.
Question 2
True or False: The presence of an emitter resistor always increases the voltage gain of a common emitter amplifier.
- True
- False
💡 Hint: Think about how stabilizing affects performance.
