An audio-frequency ideal transformer is employed to couple a 60-Ω resistance load to an electric source which is represented by a constant voltage of 6 V in series with an internal resistance of 2400 Ω.
(a) Determine the turn-ratio required to ensure maximum power transfer by matching the load and source impedances (i.e. by making the 60 Ω secondary impedance to 2400 Ω when referred to the primary).
(b) Find the load current, voltage and power under the conditions of maximum power transfer.
