Nettet8. nov. 2024 · ΦE = ΦE(top)0 + ΦE(bottom)0 + ΦE(sides) ⇒ ΦE = EA = 2πrlE. The enclosed charge is the charge contained between the two ends of the cylinder, which is the linear charge density multiplied by the length of the segment, which is the length of the cylinder. Applying Gauss's law therefore gives: ΦE = Qencl ϵo ⇒ 2πrlE = λl ϵo ⇒ E ... Nettet7. apr. 2024 · The charge density is the measure of the accumulation of electric charge in a given particular field. The following are some of the dimensions in which the charge density is measured: Linear Charge Density: λ = q l. , where q is the charge and l is the length over which it is distributed. The SI unit will be Coulomb m-1.

Yes, charge doesn't change in a Lorentz transformation. That's precisely why charge density must change in a Lorentz transformation. If in the lab frame, a length L of a wire has a (stationary) charge density of λ on it, the total charge on the wire is Q = λ L. In a frame of reference in which due to length contraction the wire is measured ...
