For a 10 KVA, 660/110 V, 60 Hz transformer, the components are given as shown below: Rp- 100 n, X, -86 0, R, -0.5 0, X =1.20, Rc= 180 KO, and XM 90 Kn. Find the equivalent and the excitation components referred to the secondary side. Xp Rc

answer for the question. Which of the following conditions would be necessary in order for you to use an r-f transformer as a very sharply tuned band-pass device? OA. A series-tuned LC circuit must be connected across the secondary winding. OB. The primary and secondary windings should be overcoupled. O C. The primary and secondary windings must be shielded from each other. OD. A capacitor should be connected between the primary and secondary windings.

A 15µF capacitor and a 470 ohm resistor are connected in series with a function generator. The supply voltage is 50V RMS 40Hz. Find the reactive power for this circuit.

A 5 to 1 ratio, step-down 10 transformer has 230/460 V secondary voltages. The secondary winding being continuously wound but with the center tap brought out. Across one half of the winding is connected an induction motor drawing 50 A at 0.72 pf and 230 V. On the other half is connected an over-excited synchronous motor drawing 40 A at 0.9 pf and 230 V. (a) Determine the current thru the center tap (b) Assuming no-loss, determine the real power at the primary side 3.
