| Abstract: | Because of the internal resistance of the electrometer,traditional resistance measurement with voltmeter-ammeter method tends to generate errors.In order to reduce measurement errors,some improved methods for measuring resistance are introduced in this paper,which leads to a more accurate result and simpler measurement process. |
