Abstract
The constants of the Krori-Barua metric (see ibid., vol.8, p.508, 1975) are explicitly fixed in terms of the physical constants of mass, charge and radius of the source. The conditions for physical relevance are investigated leading to a functional dependence of the ratio of mass-to-radius on the ratio of charge-to-mass and also to upper and lower limits on these ratios. The functional dependences of the physical variables of the problem on the fractional radius, with the square of the charge-to-mass ratio as a parameter, are presented. The information obtained regarding the Krori-Barua solution is illustrated graphically throughout.
