Using a quarter wave transformer of characteristic impedance 1 $\Omega$, a load impedance of 100 $\Omega$ will be transformed to an input impedance of value
- A. 1 $\Omega$
- B. 100 $\Omega$
- C. 0.01 $\Omega$
- D. 0.1 $\Omega$
Answer: C. 0.01 $\Omega$
Explanation: $Z_{in}(L=\frac{\lambda}{4}) = \frac{Z_0^2}{Z_L} = \frac{1^2}{100} = 0.01\text{ }\Omega$.
