Permittivity: Its unit and dimensional formula
WebJan 4, 2024 · Find the permittivity of body tissue. Answer: Since body tissue has a relative permittivity of 8 that means it's permittivity is 8 times the permittivity of a vacuum. The permittivity of vacuum/free space is ϵ0 = 8.85x10^-12 C^2/Nm^2 and that times 8 gives us roughly ϵB = 71x10^-12 C^2/Nm^2. WebMar 26, 2024 · The permittivity of free space constant ( ϵ0 ϵ 0) is a measure of the electric permittivity under ultra-high vacuum and has a value of ϵ0 = 8.85×10−12 ϵ 0 = 8.85 × 10 − 12 Farads per meter... WebSep 12, 2024 · V = Ed = σd ϵ0 = Qd ϵ0A. Therefore Equation 8.2.1 gives the capacitance of a parallel-plate capacitor as. C = Q V = Q Qd / ϵ0A = ϵ0A d. Notice from this equation that capacitance is a function only of the geometry and what material fills the space between the plates (in this case, vacuum) of this capacitor. drna275
