The intrinsic impedance of free space, often denoted by the symbol (eta_0), is given by the formula:
[
eta_0 = sqrt{frac{mu_0}{epsilon_0}}
]
where (mu_0) is the permeability of free space (vacuum permeability), and (epsilon_0) is the permittivity of free space (vacuum permittivity).
The values for these constants are:
– (mu_0 = 4pi times 10^{-7} , text{H/m}) (Henries per meter)
– (epsilon_0 approx 8.854187817 times 10^{-12} , text{F/m}) (Farads per meter)
Using these values, the intrinsic impedance of free space can be calculated as:
[
eta_0 = sqrt{frac{4pi times 10^{-7}}{8.854187817 times 10^{-12}}} approx 377 , Omega
]
Therefore, the intrinsic impedance of free space is approximately 377 Ohms.

Explanation: The intrinsic impedance is given by η = √(μo/εo) ohm. Here εo = 8.854 x 10
–
12 and μo = 4π x 10
-7
.
On substituting the values, we get η = 377 ohm
d) 377 ohm
Explanation: The intrinsic impedance is given by η = √(μo/εo) ohm. Here εo = 8.854 x 10-
12 and μo = 4π x 10-7.
On substituting the values, we get η = 377 ohm.
