31.
The L/C has the dimension of
time
capacitance
velocity
resistance
Answer: Option
Explanation:
No answer description is available. Let's discuss.
32.
The value of VSWR is taken as ∞ when the line is
short-circuited
open-circuited
terminated with full load
terminated with load equal to the characteristic impedance of the load
Answer: Option
Explanation:

For VSWR = ∞ , reflection coefficient must be 1 VSWR

if t = 1 VSWR = ∞

for t = 1, ZL = ∞

.

33.
The wavelength of an electromagnetic wave after reflection at angle on a surface
remains same as the wavelength perpendicular to the surface
remains same in the free space
increases in actual direction of propagation
decreases in actual direction of propagation
Answer: Option
Explanation:
No answer description is available. Let's discuss.
34.
A higher value of Standing Wave Ratio indicates
least mismatch between line and load
greater mismatch between load and line
number of nodes is equal to the number of antinodes
none of the above
Answer: Option
