An audio amplifier, represented by the AC source and the resistor, R, delivers alternating voltages at audio frequencies to the speaker. If the source puts out an alternating voltage of 15.0 V, the resistance, R, is 8.20 Ω and the speaker is equivalent to a resistance of 10.4 Ω. Calculate the: a) rms current of the circuit.
