Nettet15. jun. 2024 · This test is performed with an earth resistance test set that essentially comprises two circuits, as shown in Figure 1. The first circuit includes a voltage source and an ammeter, and it is brought out to the instrument’s current terminals. The second circuit includes only a voltmeter, and is brought out to the instrument’s voltage terminals. NettetIn a negative (-) earth-return system, the current flows from the positive (+) terminal to the component being operated. The component is earthed to the car body, which is earthed to the negative (-) terminal of the battery. Facebook @howacarworks Twitter @howacarworks YouTube @howacarworks.
