  2. Drude model - Wikipedia

    en.wikipedia.org/wiki/Drude_model

    The electrons arriving at location x from the higher-energy side will arrive with energies [()], while those from the lower-energy side will arrive with energies [(+)]. Here, v {\displaystyle v} is the average speed of electrons and τ {\displaystyle \tau } is the average time since the last collision.

  3. Stray voltage - Wikipedia

    en.wikipedia.org/wiki/Stray_voltage

    Stray voltage is the occurrence of electrical potential between two objects that ideally should not have any voltage difference between them. Small voltages often exist between two grounded objects in separate locations by the normal current flow in the power system. Contact voltage is a better defined term when large voltage appear as a result ...

  4. Jump wire - Wikipedia

    en.wikipedia.org/wiki/Jump_wire

    Stranded 22AWG jump wires with solid tips. A jump wire (also known as jumper, jumper wire, DuPont wire) is an electrical wire, or group of them in a cable, with a connector or pin at each end (or sometimes without them – simply "tinned"), which is normally used to interconnect the components of a breadboard or other prototype or test circuit, internally or with other equipment or components ...

  5. Speed of electricity - Wikipedia

    en.wikipedia.org/wiki/Speed_of_electricity

    Free electrons in a conductor follow a random path. Without the presence of an electric field, the electrons have no net velocity. When a DC voltage is applied, the electron drift velocity will increase in speed proportionally to the strength of the electric field. The drift velocity in a 2 mm diameter copper wire in 1 ampere current is ...

  6. Jumper (computing) - Wikipedia

    en.wikipedia.org/wiki/Jumper_(computing)

    Jumper pins (points to be connected by the jumper) are arranged in groups called jumper blocks, each group having at least one pair of contact points.An appropriately sized conductive sleeve itself called a jumper, or more technically, a shunt jumper, is slipped over the pins to complete the circuit.

  7. Electrical resistivity and conductivity - Wikipedia

    en.wikipedia.org/wiki/Electrical_resistivity_and...

    The position of the Fermi level with respect to the band structure is very important for electrical conduction: Only electrons in energy levels near or above the Fermi level are free to move within the broader material structure, since the electrons can easily jump among the partially occupied states in that region. In contrast, the low energy ...

  8. Electrostatic induction - Wikipedia

    en.wikipedia.org/wiki/Electrostatic_induction

    [4]: p.712 For example, if a positive charge is brought near the object (see picture of cylindrical electrode near electrostatic machine), the electrons in the metal will be attracted toward it and move to the side of the object facing it. When the electrons move out of an area, they leave an unbalanced positive charge due to the nuclei.

  9. Spin Hall effect - Wikipedia

    en.wikipedia.org/wiki/Spin_Hall_effect

    One can intuitively picture the intrinsic effect by using the classical analogy between an electron and a spinning tennis ball. The tennis ball deviates from its straight path in air in a direction depending on the sense of rotation, also known as the Magnus effect. In a solid, the air is replaced by an effective electric field due to ...
