Negative voltage regulation is indicative that the load is?

Last Answer : 1. Load regulation : The load regulation indicates how much the load voltage changes when the load current changes. The load regulation is defined as: % Load regulation = (VNL-VFL) / VFL *100 ... the power supply. A well-regulated power supply can have a line regulation of less than 0.1%.
