Thus I1 = and V2 = N2 N1 V1 = 40 V V1 = 1.6 A R1 Problem 2.5 The maximum power will be supplied to the load resistor when its impedance, as reflected to the primary of the ideal transformer, equals that of the source (2 kΩ). Thus the transformer turns ratio N to give maximum power must be N= Rs = 6.32 Rload Under these conditions, the source voltage will see a total resistance of Rtot = 4 kΩ and the current will thus equal I = Vs /Rtot = 2 mA.…

conducted a study on three-phase transformers containing its construction , among other characteristics link the processor it is an alternating electric current device that operates based on magnetic principles of the Laws of Faraday and Lenz , which is designed to change the parameters physical voltage, current and impedance . A variety of processors with different types of magnetic circuits , but all operate on the same principle , however , for each type of transformer there is an…
