Ayrton shunt switching principle. The Ayrton shunt or universal shunt is a high-resistance shunt used in galvanometers to increase their range [1] without changing the damping. [2] The circuit is named after its inventor William E. Ayrton. [3] Multirange ammeters that use this technique are more accurate than those using a make-before-break ...
This is an advantage, because sheet resistance of 1 Ω could be taken out of context and misinterpreted as bulk resistance of 1 ohm, whereas sheet resistance of 1 Ω/sq cannot thus be misinterpreted. The reason for the name "ohms per square" is that a square sheet with sheet resistance 10 ohm/square has an actual resistance of 10 ohm ...
The marriage took place while Ayrton was on home leave from India and Matilda was involved in the Edinburgh Seven campaign. Chaplin was awarded a posthumous honorary MBChB by the University of Edinburgh in 2019. [4] Chaplin and Ayrton's daughter was the feminist and author Edith Ayrton, wife of Israel Zangwill and mother of Oliver Zangwill. [2]
The circuit is due to Hendrik Bode who claims that the addition of the bridging resistor of a suitable value will cancel the parasitic resistance of the shunt inductor. The action of this circuit is clear if it is transformed into T topology – in this form there is a negative resistance in the shunt branch which can be made to be exactly ...
An Ayrton–Perry winding (named for William Edward Ayrton and John Perry) is a type of bifilar winding pattern used in winding wire on forms to make RF resistors. Its advantage is that the resulting coil of wire has low values of parasitic inductance and parasitic capacitance . [ 1 ]
The former component can be described with the formula , whereas represents the sheet resistance of the semiconductor substrate and the width of the metal pads. The other component that contributes to the total resistance is denoted by 2 R C {\displaystyle 2R_{C}} because when two adjacent pads are characterized two identical metallized areas ...
An alternative shunt match could be calculated after performing a Smith chart transformation from normalised impedance to normalised admittance. Point Q 20 is the equivalent of P 20 but expressed as a normalised admittance. Reading from the Smith chart scaling, remembering that this is now a normalised admittance gives
A voltage-regulator tube (VR tube) is an electronic component used as a shunt regulator to hold a voltage constant at a predetermined level. Physically, these devices resemble vacuum tubes, but there are two main differences: Their glass envelopes are filled with a gas mixture, and
