  2. Transformer types - Wikipedia

    en.wikipedia.org/wiki/Transformer_types

    Toroidal transformer. Donut-shaped toroidal transformers save space compared to E-I cores, and may reduce external magnetic field. These use a ring shaped core, copper windings wrapped around this ring (and thus threaded through the ring during winding), and tape for insulation.

  3. Zigzag transformer - Wikipedia

    en.wikipedia.org/wiki/Zigzag_transformer

    A zigzag transformer winding is a special-purpose transformer winding with a zigzag or "interconnected star" connection, such that each output is the vector sum of two (2) phases offset by 120°. [1]

  4. Transformer - Wikipedia

    en.wikipedia.org/wiki/Transformer

    In electrical engineering, a transformer is a passive component that transfers electrical energy from one electrical circuit to another circuit, or multiple circuits.A varying current in any coil of the transformer produces a varying magnetic flux in the transformer's core, which induces a varying electromotive force (EMF) across any other coils wound around the same core.

  5. Delta-wye transformer - Wikipedia

    en.wikipedia.org/wiki/Delta-wye_transformer

    An example delta-wye transformer schematic. A delta-wye transformer is a type of three-phase electric power transformer design that employs delta-connected windings on its primary and wye/star connected windings on its secondary.

  6. Learning styles - Wikipedia

    en.wikipedia.org/wiki/Learning_styles

    Learning styles refer to a range of theories that aim to account for differences in individuals' learning. [1] Although there is ample evidence that individuals express personal preferences on how they prefer to receive information, [2]: 108 few studies have found validity in using learning styles in education.

  7. Isolation transformer - Wikipedia

    en.wikipedia.org/wiki/Isolation_transformer

    A 230 V isolation transformer A simple 1:1 isolation transformer with an extra dielectric barrier and an electrostatic shield between primary and secondary. The grounded shield prevents capacitive coupling between primary and secondary windings.

  8. Transfer learning - Wikipedia

    en.wikipedia.org/wiki/Transfer_learning

    Transfer learning (TL) is a technique in machine learning (ML) in which knowledge learned from a task is re-used in order to boost performance on a related task. [1] For example, for image classification, knowledge gained while learning to recognize cars could be applied when trying to recognize trucks.

  9. Learning theory (education) - Wikipedia

    en.wikipedia.org/wiki/Learning_theory_(education)

    A classroom in Norway. Learning theory describes how students receive, process, and retain knowledge during learning.Cognitive, emotional, and environmental influences, as well as prior experience, all play a part in how understanding, or a worldview, is acquired or changed and knowledge and skills retained.
