    Exercises with voltage and power

    Can you tell me if my result results are correct, and if there are errors where are they? I used the symbol rms to indicate the root-mean-square, Avo is open-circuit voltage gain, Ap is the power gain, Rl is the load resistance. i stands for input, s for source and o per output. > 1) A sensor...
