Question

ideal transformer in Fig. 9 has 500 turns on the ary. The source produces a voltage Eg of 600 V, and the load Z is a resistance of 12 . Calculate the following: a. The voltage E2 b. The current /2 c. The current I d. The power delivered to the primary [W e. The power output from the secondary WT In Problem 4, what is the impedance seen by the source Eg? primary and 300 turns on the second- 5

I only need problem 5 please help I think I know how to do it but just want to be sure.

Answer 1

5) Impedance seen by source Eg is

$Z'=Z \times \left ( \frac{N_{_{1}}}{N_2} \right )^{2}$

$=12 \times\left ( \frac{500}{300} \right )^{2}$

= 33.33 $\Omega$

Thus, the impedance seen by the source Eg is 33.33 $\Omega$
