The rings of Saturn, being immersed in a plasma and exposed to ultraviolet radiation from the sun, will be electrically charged. The charging of the rings is studied through the numerical solution of the Boltzmann equation. The work includes the effect of plasma loss and photoelectron production within the rings. Several aspects of the ring structure (thickness, average particle size, cross sectional profile, and optical depth) can be varied to illustrate the effect of these parameters on the resulting charge. The solution for several cases at low plasma density and high plasma density are presented. The results have implications for several processes occurring in the rings. The amount of current carried by the rings may be an order of magnitude larger than the amount estimated by charging studies which use a flat plate description of the rings. If spokes form, the rings must be very thin with tightly packed particles. The disruption and accretion of small dust grains within the rings may be greatly enhanced by the strong electric fields there. The charging processes considered here are probably not the source of the Saturn Electrostatic Discharge ratio emissions although they may contribute to the lower frequency portion of the Saturn Kilometric Radiation emissions.
