The value of Z1‘ in terms of Z1, Z2 from the circuits shown in question 3 is?$

A. Z<sub>1</sub><sup>‘</sup>=(m Z<sub>2</sub>(Z<sub>2</sub> 4 m)/(1-m<sup>2</sup> ))/m Z<sub>1</sub>(Z<sub>2</sub> 4 m/(1-m<sup>2</sup> ))
B. Z<sub>1</sub><sup>‘</sup>=(m Z<sub>1</sub>(Z<sub>2</sub> 4 m)/(1-m<sup>2</sup> ))/m Z<sub>2</sub>(Z<sub>2</sub> 4 m/(1-m<sup>2</sup> ))
C. Z<sub>1</sub><sup>‘</sup>=(m Z<sub>1</sub>(Z<sub>2</sub> 4 m)/(1-m<sup>2</sup> ))/m Z<sub>1</sub>(Z<sub>2</sub> 4 m/(1-m<sup>2</sup> ))
D. Z<sub>1</sub><sup>‘</sup>=(m Z<sub>1</sub>(Z<sub>2</sub> 4 m)/(1-m<sup>2</sup> ))/m Z<sub>1</sub>(Z<sub>1</sub> 4 m/(1-m<sup>2</sup> ))
Answer» D. Z<sub>1</sub><sup>‚Äö√Ñ√∂‚àö√ë‚àö‚â§</sup>=(m Z<sub>1</sub>(Z<sub>2</sub> 4 m)/(1-m<sup>2</sup> ))/m Z<sub>1</sub>(Z<sub>1</sub> 4 m/(1-m<sup>2</sup> ))
