A) 183 \[\Omega \]
B) 273 \[\Omega \]
C) 405 \[\Omega \]
D) 363 \[\Omega \]
E) 377 \[\Omega \]
Correct Answer: E
Solution :
In case of dielectric (conductivity = 0) wave impedance of free space \[{{Z}_{0}}=\sqrt{\frac{\mu }{{{\varepsilon }_{0}}}}\] For free space, \[\mu =4\pi \times {{10}^{-7}}H/m\] and \[{{\varepsilon }_{0}}=8.54\times {{10}^{-12}}F/m\] so, \[{{Z}_{0}}\simeq 377\,\Omega \]You need to login to perform this action.
