Ayrton Shunt
Ayrton shunt or universal shunt is a high-resistance shunt used in galvanometers to increase their range without changing the damping. The circuit is named after its inventor William E. Ayrton. Multirange ammeters that use this technique are more accurate than those using a make-before-break switch. Also it will eliminate the possibility of having a meter without a shunt which is a serious concern in make-before-break switches. The selector switch changes the amount of resistance in parallel with Rm (meter resistance). The voltage drop across parallel branches is always equal. When all resistances are placed in parallel with Rm maximum sensitivity of ammeter is reached. Ayrton shunt is rarely used for currents above 10 amperes The ampere (, ; symbol: A), often shortened to amp,SI supports only the use of symbols and deprecates the use of abbreviations for units. is the unit of electric current in the International System of Units (SI). One ampere is equal to elect .... ...

Leeds & Northrup Ayrton Shunt
Leeds () is a city and the administrative centre of the City of Leeds district in West Yorkshire, England. It is built around the River Aire and is in the eastern foothills of the Pennines. It is also the third-largest settlement (by population) in England, after London and Birmingham. The city was a small manorial borough in the 13th century and a market town in the 16th century. It expanded by becoming a major production centre, including of carbonated water where it was invented in the 1760s, and trading centre (mainly with wool) for the 17th and 18th centuries. It was a major mill town during the Industrial Revolution. It was also known for its flax industry, iron foundries, engineering and printing, as well as shopping, with several surviving Victorian era arcades, such as Kirkgate Market. City status was awarded in 1893, a populous urban centre formed in the following century which absorbed surrounding villages and overtook the nearby York population. It is located ab ...
