1) In terms of potential difference V, electric current i, Permittivity ϵ0 , permeability μ0 and speed of light c, the dimensionally correct equations is /are A) μ0I2=ϵ0V2 B) ϵ0I=μ0I C) I=ϵ0cV D) μ0cI=ϵ0V Answer: Option A,CExplanation: (A) Energy of inductor 12LI2=12μ0N2AlI2e Energy of capacitor 12CV2=12ϵ0AdV2μ0AlI2 and ϵ0AdV2 have same dimensions. So, μ0I2 and ϵ0V2 have same dimensions. (C) Q=CV⇒Qt=CVt I=ϵ0AlVt Alt have unit of speed so, I=ϵ0cV
