There is a resulting division of current, enabling the measurement of the amperage level. As an example, consider a microcontroller used to control a DC motor with a transistor controlled by a PWM output. No, I think there could be a couple of reasons, some might be too embarrassed to post, or in my case, I just saw the thread. If you want to regulate a constant current supply, you adjust a SHUNT resistor in parallel with the load. Optimized shunt solution for low drift and a 1% accurate shunt-based DC metering of both current and voltage. Current shunts can be supplied with certified AC/DC corrections from NPL for traceability directly to international standards. AD8479 AD7779 This is the underlying principle behind the current shunt. The key is applying the basic principle of the current shunt with the correct hardware for your application, which will ensure that any measurements taken are reliable and safe. When I learned Ohms law it was U (Im from Sweden though so that might explain it :), I learned it as U=IR, could have been a Dutch thing (My stupid head made the mnemonic Ultraviolet = InfraRed to remember the order). Anyone? Other times, a very accurate current shunt may be desired during the bench testing of equipment. Site by: Ed Doherty Jr. | Menu by: Apycom, 200-Series Reference Standards Oil (25 C). PCS-1000I will replace non-isolated output PCS-1000 models, which will be discontinued.
