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.
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.
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 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.
English: Kelvin Bridge Span on a gravel county road is being replaced by the bridge under construction on the right. This is an image of a place or building that is listed on the National Register of Historic Places in the United States of America .
Kelvinbridge is the common name of the Great Western Bridge, a cast iron road and pedestrian bridge located in the West End of the city of Glasgow, Scotland, built to carry the Great Western Road (A82) at a high level across the River Kelvin. [2]
