As shown in the circuit diagram below, an AC source delivers an alternating voltage at audio frequencies to a speaker connected to the source through a resistor. The source voltage has an amplitude of 13.0 V, the resistance R = 6.30 0, and the speaker is equivalent to a resistance of 10.4 N. Determine the time-averaged power (in W) transferred to the speaker. R Speaker 6.2949 See if you can express the average power in terms of the rms current in the circuit and the resistance equivalent of the speaker. Then express the rms current in terms of the maximum voltage and the total resistance in the circuit, When finding the rms current, be sure to account for both the fixed resistance in the circuit and the resistance equivalent of the speaker.
