The intrinsic impedance of free space is given by

Electronics and Communication Engineering (ECE) : Electromagnetic Field Theory - Quiz(MCQ)

272 ohm

377 ohm

412 ohm

740 ohm

Correct Answer : Option (B) : 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.
