  2. Electrostatic induction - Wikipedia

    en.wikipedia.org/wiki/Electrostatic_induction

    This charge neutralizes the charge in the gold leaves, so the leaves come together again. The electroscope now contains a net charge opposite in polarity to that of the charged object. When the electrical contact to earth is broken, e.g. by lifting the finger, the extra charge that has just flowed into the electroscope cannot escape, and the ...

  3. Body capacitance - Wikipedia

    en.wikipedia.org/wiki/Body_capacitance

    Body capacitance was a significant nuisance when tuning the earliest radios; touching the tuning knob controlling the tuner's variable capacitor would couple the body capacitance into the tuning circuit, slightly changing its resonant frequency. Design of such circuits intended to be adjusted by a user must prevent interaction of the user's ...

  4. Charge carrier - Wikipedia

    en.wikipedia.org/wiki/Charge_carrier

    In conducting mediums, particles serve to carry charge. In many metals, the charge carriers are electrons. One or two of the valence electrons from each atom are able to move about freely within the crystal structure of the metal. [4] The free electrons are referred to as conduction electrons, and the cloud of free electrons is called a Fermi gas.

  5. Electrostatics - Wikipedia

    where = is the distance of each charge from the test charge, which situated at the point , and () is the electric potential that would be at if the test charge were not present. If only two charges are present, the potential energy is Q 1 Q 2 / ( 4 π ε 0 r ) {\displaystyle Q_{1}Q_{2}/(4\pi \varepsilon _{0}r)} .

  6. List of electrical phenomena - Wikipedia

    en.wikipedia.org/wiki/List_of_electrical_phenomena

    Electric shock — Physiological reaction of a biological organism to the passage of electric current through its body. Ferranti effect — A rise in the amplitude of the AC voltage at the receiving end of a transmission line , compared with the sending-end voltage, due to the capacitance between the conductors, when the receiving end is open ...

  7. Faraday's ice pail experiment - Wikipedia

    en.wikipedia.org/wiki/Faraday's_ice_pail_experiment

    The container is discharged by connecting it briefly to a large conducting object, called a ground (earth); this can be done by touching it with a finger, using the conductive human body as a ground. Any initial charge drains off into the ground. The charge detector reads zero, indicating that the container has no charge.

  9. Charge transport mechanisms - Wikipedia

    en.wikipedia.org/wiki/Charge_transport_mechanisms

    Similar to electron conduction, the electrical resistance of thin-film electrolytes depends on the applied electric field, such that when the thickness of the sample is reduced, the conductivity improves due to both the reduced thickness and the field-induced conductivity enhancement.
