For the circuit shown in the figure, find a value for a so that the maximum power is transferred to the speaker.
Find Z if Z = 16030.
The 4 ohm load in the circuit is absorbing four times as much average power as the 25 ohm load. The two loads are matched to a sinusoidal source that has an internal impedance of 5000 ohms.
a) Specify the numerical value of a.
b) Calculate the power delivered to the 25 ohm load.
c) Calculate the RMS value of the voltage across the resistor.
