The relative permittivity of free space is given by__________?
Correct answer: A. 1
- A. 1
- B. 10
- C. 100
- D. 1000
Explanation
Relative permittivity is the ratio of a material's permittivity to the permittivity of free space, so free space itself has a relative permittivity of 1. Its absolute permittivity is ε₀, approximately 8.854 × 10⁻¹² F/m.
