1. The problem statement, all variables and given/known data For a function ρ(x,y,z) = cδ(x-a), give the meaning of the situation and describe each variable. 2. Relevant equations As far as units go, I know that: ρ(x,y,z) = charge density = C/ m^3 δ(x-a) = 1/m and if those two are correct, then b must have units of (C/m^2), which is some sort of surface charge distribution. 3. The attempt at a solution I'm new to delta dirac functions and my understanding is very superficial. When the function is not inside an integral, I especially don't understand it! I think that "a" represents some sort of center point where there is infinite charge density, and x is the distance from the center. Any guidance would be greatly appreciated.
