Question
In terms of potential difference V, electric current I, permittivity ε0, permeability μ0 and speed of light c, the dimensionally correct equation(s) is(are)
Options
A.μ0I2 = ε0V2
B.μ0I = ε0V
C.μ0I = ε0cV
D.μ0cI = ε0V
Solution
Using C = 
we can check the correctness.
(A) μ0I2 = ∈0V2
= R2
R2 = R2 correct
(B) ∈0I = μ0V
= R not correct
(C) I = ∈0cV
correct
(D) μ0CI = ∈0V
∴
= R incorrect
