Notation of permittivity in farads per meter question

Click For Summary
SUMMARY

The discussion centers on the notation of electrical permittivity of free space, ε0, expressed in farads per meter (Fm-1). The notation indicates that permittivity is measured as capacitance (farads) per unit length (meters), where the superscript -1 signifies the inverse relationship. This clarification highlights the importance of understanding unit notation in physics, particularly in electromagnetism.

I am using an old textbook as a reference, and the equation given for the electrical permittivity of free space ε0 is given in terms of:

(Fm-1)

where this measurement notation represents farads per meter. Why the superscript of -1 in the notation?
 
Physics news on Phys.org
x^(-1) = 1/x

Fm(-1) = F/m

Are you sure you didn't already know that?
 
Oh, geesh. Duh. Yeah, I knew that. Thanks!
