2.

A loss less line of characteristic impedance Z0 is terminated in pure reactance of -jZ0 value. VSWR is

 [A]. 10 [B]. 2 [C]. 1 [D]. infinity

Explanation:

A pure reactance does not absorb any power.

Therefore VSWR is infinite because |rv| = 1.

 Faizz said: (May 25, 2016) Can I get some information about VSWR?

 Gurpreet Kaur said: (Jun 7, 2016) @Faizz. VSWR means Voltage Standing Wave Ratio = (1 + |rho v|) / (1 - |rho v|). Here (rho v) is (reflected power)/(incident power).

 Swetha said: (Sep 27, 2016) VSWR = (1 + rho)/(1 - rho), rho = (ZL - Z0)/(ZL + Z0).

 Swetha said: (Sep 27, 2016) VSWR = (1 + rho)/(1 - rho), rho = (ZL - Z0)/(ZL + Z0).

 Vinay said: (Dec 3, 2016) How? Explain it in clear.

 Guru said: (Dec 6, 2016) What's that RHO?

 Roli said: (Apr 14, 2017) Reflection coefficient is ρ.

 Vineet said: (Apr 3, 2018) In that expression of VSWR, it is the magnitude of reflection coefficient |ρ|.
