If Z1, Z2 are same type of reactance, then |Z1/4 Z2| is real, then the value of α is?$

A. α = sinh<sup>-1</sup>⁡√( Z<sub>1</sub>/4 Z<sub>2</sub>)
B. α = sinh<sup>-1</sup>⁡⁡√( Z<sub>1</sub>/Z<sub>2</sub>)
C. α = sinh<sup>-1</sup>⁡√( 4 Z<sub>1</sub>/Z<sub>2</sub>)
D. α = sinh<sup>-1</sup>⁡⁡√( Z<sub>1</sub>/2 Z<sub>2</sub>)
Answer» B. ‚âà√≠¬¨¬± = sinh<sup>-1</sup>‚Äö√Ñ√∂‚àö√ñ¬¨‚àû‚Äö√Ñ√∂‚àö√ñ¬¨‚àû‚Äö√Ñ√∂‚àö‚Ć‚àö‚àÇ( Z<sub>1</sub>/Z<sub>2</sub>)
