A Kelvin bridge, also called a Kelvin double bridge and in some countries a Thomson bridge, is a measuring instrument used to measure unknown electrical resistors below 1 ohm. It is specifically designed to measure resistors that are constructed as four terminal resistors.
The best-known bridge circuit, the Wheatstone bridge, was invented by Samuel Hunter Christie and popularized by Charles Wheatstone, and is used for measuring resistance. It is constructed from four resistors, two of known values R 1 and R 3 (see diagram), one whose resistance is to be determined R x, and one which is variable and calibrated R 2.
In the semiconductor industry, Cross-Bridge Kelvin Resistor(CBKR) structures are the mostly used test structures to characterize metal-semiconductor contacts in the Planar devices of VLSI technology. During the measurement process, force the current ( I {\displaystyle I} ) between contacts 1 and 2 and measure the potential deference between ...
Original eyebars were formed from "piling" [2] thin iron metal on top of one another and forging it together in a furnace. Once together the piece was heated and hammered into a U shape over a die. To create the eye the heated bent iron was hammered into itself closing the gap and creating the eye shape. [2]
The final stage of a Kelvin–Varley divider is just a Kelvin divider. For a decade divider, there will be ten equal value resistors. Let the value of each resistor be R n Ohms. The input impedance of the entire string will be 10 R n. Alternatively, the last stage can be a two resistor bridge tap.
Binnacle with iron correcting spheres at each side and clinometer below compass Modern binnacle with compass A binnacle ( / ˈ b ɪ n ə k əl / ) is a waist-high case or stand on the deck of a ship , generally mounted in front of the helmsman , in which navigational instruments are placed for easy and quick reference as well as to protect the ...
The Kelvin water dropper, invented by Scottish scientist William Thomson (Lord Kelvin) in 1867, [1] is a type of electrostatic generator. Kelvin referred to the device as his water-dropping condenser. The apparatus is variously called the Kelvin hydroelectric generator, the Kelvin electrostatic generator, or Lord Kelvin's thunderstorm.
Anderson's bridge. In electronics, Anderson's bridge is a bridge circuit used to measure the self-inductance of the coil. It enables measurement of inductance by utilizing other circuit components like resistors and capacitors. [1] Anderson's bridge was invented by Alexander Anderson in 1891. [2]
