  2. Four-terminal sensing - Wikipedia

    en.wikipedia.org/wiki/Four-terminal_sensing

    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 ...

  3. Contact resistance - Wikipedia

    en.wikipedia.org/wiki/Contact_resistance

    Because contact resistance is usually comparatively small, it can be difficult to measure, and four-terminal measurement gives better results than a simple two-terminal measurement made with an ohmmeter. In a two-terminal measurement (as with a typical ohmmeter), the current used to make the measurement is injected through the measurement leads ...

  4. Kelvin bridge - Wikipedia

    en.wikipedia.org/wiki/Kelvin_bridge

    The operation of the Kelvin bridge is very similar to the Wheatstone bridge, but uses two additional resistors. Resistors R 1 and R 2 are connected to the outside potential terminals of the four terminal known or standard resistor R s and the unknown resistor R x (identified as P 1 and P′ 1 in the diagram).

  5. Multiway switching - Wikipedia

    en.wikipedia.org/wiki/Multiway_switching

    A "4-way" (intermediate) switch is a purpose built double pole, double throw (DPDT) switch, internally wired in manufacture to reverse the connections between the input and output and having only four external terminals. This switch has two pairs of "traveler" terminals that it connects either straight through, or crossed over (transposed, or ...

  6. Electrical resistance and conductance - Wikipedia

    An ohmmeter could be used to verify this value. Substances in which electricity can flow are called conductors. A piece of conducting material of a particular resistance meant for use in a circuit is called a resistor. Conductors are made of high-conductivity materials such as metals, in particular copper and aluminium. Resistors, on the other ...

  9. Lang factor - Wikipedia

    en.wikipedia.org/wiki/Lang_factor

    It is widely used in industrial engineering to calculate the capital and operating costs of a plant. [1] [2] [3] The factors were introduced by H. J. Lang and Dr Micheal Bird in Chemical Engineering magazine in 1947 as a method for estimating the total installation cost for plants and equipment.
