Topic: Electromagnetics
VSWR of a purely resistive load of normalized value $n+j0$ for $n<1$ is
- A. n
- B. $1/n$
- C. 1
- D. infinite
Answer: B. $1/n$
Explanation: For a purely resistive network, VSWR = $Z_L/Z_0$ if $Z_L > Z_0$ and VSWR = $Z_0/Z_L$ if $Z_L < Z_0$. Here, the normalized load is $n < 1$, which means $Z_L < Z_0$. Therefore, $\text{VSWR} = 1/n$.
