Step 1

The efficiency of the amplifier would not necessarily be higher if the emitter resistor were replaced with the load resistor (speaker). In fact, it would likely decrease because the load resistor would draw more current and cause more power dissipation in the Show more…

1a. Would the efficiency of the amplifier be higher if the emitter resistor were replaced with the load resistor (speaker)? What is the disadvantage? 1b. Would the efficiency of the amplifier be high if the input signal is larger? 2. What is the advantage of the Darlington arrangement for the CC amplifier?
