MCQ (Single Correct Answer)

-0.6

A load, Z_L = R_L + jX_L is to be matched, using an ideal transformer, to a generator of internal impedance, Z_S = R_S + jX_S. The turns ratio of the transformer required is

$$\sqrt{\left|Z_\mathrm S\;/\;Z_\mathrm L\right|}$$

$$\sqrt{\left|R_\mathrm L\;/\;R_\mathrm S\right|}$$

$$\sqrt{\left|R_\mathrm L\;/\;Z_\mathrm S\right|}$$

$$\sqrt{\left|{\mathrm Z}_\mathrm L\;/\;R_\mathrm S\right|}$$
