Shunt measurement
Thomas-type shunts are still used as secondary standards to take very accurate current measurements, as using quantum Hall effect is a time-consuming process. The accuracy of these types of shunts is measured in the ppm and sub-ppm scale of drift per year of set resistance. See more In electronics, a shunt is a device that creates a low-resistance path for electric current, to allow it to pass around another point in the circuit. The origin of the term is in the verb 'to shunt' meaning to turn away or follow a different … See more In photovoltaics, the term is widely used to describe an unwanted short circuit between the front and back surface contacts of a See more Capacitors are used as shunts to redirect high-frequency noise to ground before it can propagate to the load or other circuit components. See more Where devices are vulnerable to reverse polarity of a signal or power supply, a diode may be used to protect the circuit. If connected in series … See more One example is in miniature Christmas lights which are wired in series. When the filament burns out in one of the incandescent light bulbs, the full line voltage appears … See more A gas-filled tube can also be used as a shunt, particularly in a lightning arrester. Neon and other noble gases have a high breakdown voltage, … See more The term shunt is used in filter and similar circuits with a ladder topology to refer to the components connected between the line and common. … See more WebCurrent measurement using a shunt resistor and voltmeter is particularly well-suited for applications involving particularly large magnitudes of current. In such applications, the shunt resistor’s resistance will likely be in the order of milliohms or microohms, so that only a modest amount of voltage will be dropped at full current.
