Chapter 23, Problem 14P

For the transformer in Fig. 23.61, determine

1. the equivalent resistance R_e.
2. the equivalent reactance X_e.
3. the equivalent circuit reflected to the primary.
4. the primary current for $V_g=50V< 0^{\circ }$
5. the load voltage V_L.
6. the phasor diagram Of the reflected primary circuit.
7. the new load voltage if we assume the transformer to be ideal with a 4 : 1 turns ratio. Compare the result with that of part (e).
