Don't forget to take into account losses 6 Oct 2010 The voltage variation across the terminals of an RC load on a rectifier depends on the loss of charge on the condenser between charging impulses, and so depends on the magnitude of current drain to the follower circuit and also on whether the rectifier is half-wave or full-wave. With either half-wave or
