Question 1:

For the common emitter amplifier circuit, what is the effect on the voltage gain, A, by increasing RL?

Answer 1:

Following emitter amplifier circuit gain equation presented in the first section of the lab activity:

We notice that the RL value is directly proportional with the voltage gain A, therefore increasing the value of RL will lead to a larger voltage at the output of the common emitter amplifier.
