23-1 4 pts An audio amplifier, represented by the ac source and resistor in the figure, delivers to the speaker alternating voltage at audio frequencies. R If the source voltage has an amplitude of 15.0 V, R = 8.20, and the speaker is equivalent to a resistance of 12.0 2what time-averaged power is transferred to it? W (± 0.02 W) 23-2 4 pts An inductor is connected to a 20.0-Hz sinusoidal power supply that produces a 50.0- V peak voltage. What inductance is needed to keep the instantaneous current in the circuit below 60.2 mA? H (± 0.02 H)
