A 75 ohm line is first short terminated and minima locations are noted. Then the short is replaced by resistive load and minima location are again noted. If minima location are not altered and VSWR is 3, the value of resistive load is

• 25 Ω
• 50 Ω
• 225 Ω
• 250 Ω

Correct Answer: 225 Ω

Explanation:

r_v and VSWR .
