  2. Inductive charging - Wikipedia

    en.wikipedia.org/wiki/Inductive_charging

    Inductive charging (also known as wireless charging or cordless charging) is a type of wireless power transfer. It uses electromagnetic induction to provide electricity to portable devices. Inductive charging is also used in vehicles, power tools, electric toothbrushes, and medical devices.

  3. Electrostatic induction - Wikipedia

    en.wikipedia.org/wiki/Electrostatic_induction

    Using an electroscope to show electrostatic induction. The device has leaves/needle that become charged when introducing a charged rod to it. The leaves bend the leave/needle, and the stronger the static introduced, the more bending occurs. However, the induction effect can also be used to put a net charge on an object.

  4. Wireless power transfer - Wikipedia

    en.wikipedia.org/wiki/Wireless_power_transfer

    Inductive coupling is the oldest and most widely used wireless power technology, and virtually the only one so far which is used in commercial products. It is used in inductive charging stands for cordless appliances used in wet environments such as electric toothbrushes [57] and shavers, to reduce the risk of electric shock. [78]

    Wireless charging is making some serious headway in public mindshare. Once confined to toothbrushes and other simple household items, it's now a handy means of powering phones (HP's Touchstone ...

  6. Electromagnetic induction - Wikipedia

    en.wikipedia.org/wiki/Electromagnetic_induction

    Electromagnetic or magnetic induction is the production of an electromotive force (emf) across an electrical conductor in a changing magnetic field. Michael Faraday is generally credited with the discovery of induction in 1831, and James Clerk Maxwell mathematically described it as Faraday's law of induction .

  7. Qi (standard) - Wikipedia

    en.wikipedia.org/wiki/Qi_(standard)

    Qi (/ tʃ iː / CHEE) is an open standard for inductive charging developed by the Wireless Power Consortium.It allows compatible devices, such as smartphones, to receive power when placed on a Qi charger, which can be effective over distances up to 4 cm (1.6 in). [1]

  8. Plugless Power - Wikipedia

    en.wikipedia.org/wiki/Plugless_Power

    Plugless Power [1] is a family of Electric Vehicle Supply Equipment (EVSE) products manufactured by Plugless Power, Inc. that enable wireless (inductive) charging for electric vehicles (WCEV). The Plugless Power EVSE wirelessly delivers electrical power to the on-board EV battery charger using electromagnetic induction without a physical ...

  9. Electrophorus - Wikipedia

    en.wikipedia.org/wiki/Electrophorus

    Charge conservation while using an electrophorus.. Charge in the universe is conserved. The electrophorus simply separates positive and negative charges. A positive or negative charge ends up on the metal plate (or other storage conductor), and the opposite charge is stored in another object after grounding (in the earth or the person touching the metal plate).
