engineering recuitment HPCL Engineer Mock Test 2024 Electromagnetic Theory Transmission Lines Standing Wave Ratio
A 75 Ω transmission line is first short-terminated and the minima locations are noted. When the short is replaced by a resistive load RL, the minima locations are not altered and the VSWR is measured to be 3. The value of RL is
1
25 Ω
2
50 Ω
3
225 Ω
4
250 Ω
