The transformer is assumed to be ideal. a) Calculate the missing quantities (V 2 , V 1 , number of primary turns N 1 , and the phase angle of the source voltage) if the impedance Z 1 is not present . b) Draw the phasor diagram of all the voltages and currents in the circuit for case a). Use the following scaling for the diagram: 125 V/inch, 2.5 A/inch c) Calculate the complex, the real, and the reactive power as well as the power factor (leading/lagging?) at the source for case a). Draw the power triangle to scale with
