Abstract
A resistive voltage divider includes first and second resistors, which are electrically connected in series and are made of a resistive film material which is applied in the form of a trace onto an insulating substrate. The divider's voltage ratio has a value between ten and one million. To improve the accuracy of the voltage divider, the first and second resistors are made of the same resistive film material, have a trace length above a corresponding specific trace length, and have approximately the same trace width.
