The recent paper by Arnaut  derived statistical distributions for power dissipation inside linear or nonlinear circuit elements driven by a circuit source and illuminated by an external random electromagnetic field. Arnaut  derived probability density functions (pdfs) of the normalized power dissipated inside rectilinear, planar and volumetric resistive elements for various canonical representations. However, several of the pdfs, denoted by fS(·), were left unevaluated in the form of integrals. Here, I would like to point out that at least one of these integrals can be reduced to a closed form. Consider equation (12) of Arnaut :
for m > 1, where Iν(·) denotes the modified Bessel function of the first kind of order ν. Setting y = , one can rewrite (1) as
where n = [(m − 1) q − 1] + 1.
