  2. Potentiometer - Wikipedia

    en.wikipedia.org/wiki/Potentiometer

    A potentiometer with a resistive load, showing equivalent fixed resistors for clarity. The potentiometer can be used as a voltage divider to obtain a manually adjustable output voltage at the slider (wiper) from a fixed input voltage applied across the two ends of the potentiometer. This is their most common use.

  3. Potentiometer (measuring instrument) - Wikipedia

    en.wikipedia.org/wiki/Potentiometer_(measuring...

    A potentiometer being calibrated and then measuring an unknown voltage. R 1 is the resistance of the entire resistance wire. The arrow head represents the moving wiper.. In this circuit, the ends of a uniform resistance wire R 1 are connected to a regulated DC supply V S for use as a voltage divider.

  4. Potentiostat - Wikipedia

    en.wikipedia.org/wiki/Potentiostat

    A potentiostat is a control and measuring device. It comprises an electric circuit which controls the potential across the cell by sensing changes in its resistance, varying accordingly the current supplied to the system: a higher resistance will result in a decreased current, while a lower resistance will result in an increased current, in order to keep the voltage constant as described by ...

  5. String potentiometer - Wikipedia

    en.wikipedia.org/wiki/String_potentiometer

    The string potentiometer may be connected as a three-wire tapped resistor (voltage divider), in a control circuit, or may be packaged with electronics to produce a measurement signal in a useful form, such as a variable voltage 0-10 VDC, variable current 4-20mA, pulse encoder, Bus (DeviceNet and Canbus) and RS-232 communications.

  6. Motorized potentiometer - Wikipedia

    en.wikipedia.org/wiki/Motorized_potentiometer

    The M9 Gun Director had a potentiometer controlled by op amps. [5] The Bomben-Abwurfrechner BT-9 has a motor driven potentiometer to convert a pressure into a potentiometer setting. [6] In 1968 a patent was filled describing a motor-potentiometer combination where the motor only engages when energized, allowing manual operation. [7]

  7. Hall effect - Wikipedia

    en.wikipedia.org/wiki/Hall_effect

    The Hall effect is the production of a potential difference (the Hall voltage) across an electrical conductor that is transverse to an electric current in the conductor and to an applied magnetic field perpendicular to the current.

  8. Potential energy - Wikipedia

    en.wikipedia.org/wiki/Potential_energy

    There are various types of potential energy, each associated with a particular type of force. For example, the work of an elastic force is called elastic potential energy; work of the gravitational force is called gravitational potential energy; work of the Coulomb force is called electric potential energy; work of the strong nuclear force or weak nuclear force acting on the baryon charge is ...

  9. Elastic energy - Wikipedia

    en.wikipedia.org/wiki/Elastic_energy

    Elastic energy is the mechanical potential energy stored in the configuration of a material or physical system as it is subjected to elastic deformation by work performed upon it. Elastic energy occurs when objects are impermanently compressed, stretched or generally deformed in any manner.
