 P: 223 1. The problem statement, all variables and given/known data Speaker Resistance = 10.4 Ohm R = 8.20 Ohm Maximum voltage of AC source = 15.0 V What's the average power transferred to the speaker? 2. Relevant equations P = $I^2R$ Imax = $I/2^0.5$ 3. The attempt at a solution I could the problem if there was only the speaker resistance. I don't understand how the other resistance comes into play or what it does in the circuit.
