What is the SI unit and dimension of permittivity of vacuum?
What is the SI unit and dimension of permittivity of vacuum?
Permittivity = [Charge]2 × [Force]–1 × [Distance]–2. Or, ε = [I1 T1]2 × [M1 L1 T-2]–1 × [M0 L1 T0]–2 = [M-1 L-3 T4 I2] Therefore, the permittivity of free space or vacuum is dimensionally represented as M-1 L-3 T4 I2.
