To overcome this, a second pair of resistors R′ 1 and R′ 2 form a second pair of arms of the bridge (hence 'double bridge') and are connected to the inner potential terminals of R s and R x (identified as P 2 and P′ 2 in the diagram). The detector D is connected between the junction of R 1 and R 2 and the junction of R′ 1 and R′ 2. [2]
In power supply design, a bridge circuit or bridge rectifier is an arrangement of diodes or similar devices used to rectify an electric current, i.e. to convert it from an unknown or alternating polarity to a direct current of known polarity. In some motor controllers, an H-bridge is used to control the direction the motor turns.
Four-point measurement of resistance between voltage sense connections 2 and 3. Current is supplied via force connections 1 and 4. In electrical engineering, four-terminal sensing (4T sensing), 4-wire sensing, or 4-point probes method is an electrical impedance measuring technique that uses separate pairs of current-carrying and voltage-sensing electrodes to make more accurate measurements ...
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.
The double bridge with its two rows of arches, one on top of the other, was probably built around 1330. It lies at the foot of the southwestern valley side below Rothenburg ob der Tauber and was part of a trade route from Augsburg to Würzburg. In terms of building activity, it is known that it was renovated in 1791, after the four upper arches ...
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.
The Schering bridge is an electrical circuit used for measuring the insulating properties of electrical cables and equipment. [1] It is an AC bridge circuit , developed by Harald Schering . It has the advantage that the balance equation is independent of frequency.
A Maxwell-Wien bridge. A Maxwell bridge is a modification to a Wheatstone bridge used to measure an unknown inductance (usually of low Q value) in terms of calibrated resistance and inductance or resistance and capacitance. [1] When the calibrated components are a parallel resistor and capacitor, the bridge is known as a Maxwell bridge.
