  2. Center tap - Wikipedia

    en.wikipedia.org/wiki/Center_tap

    For example, a 24 VCT transformer will measure 24 VAC across the outer two taps (winding as a whole), and 12 VAC from each outer tap to the center-tap (half winding). These two 12 VAC supplies are 180 degrees out of phase with each other, measured with respect to the tap, thus making it easy to derive positive and negative 12 volt DC power ...

    In 1998, Fisher-Price undertook a monumental recall of up to 10 million Power Wheels 12 volt and Super 6 volt vehicles manufactured since 1986. [citation needed] The recall and repair program was conducted to replace battery fuses and strengthen battery connectors in order to prevent the units from overheating. The main difference of a post ...

  5. Coupling (electronics) - Wikipedia

    en.wikipedia.org/wiki/Coupling_(electronics)

    In electronics, electric power and telecommunication, coupling is the transfer of electrical energy from one circuit to another, or between parts of a circuit. Coupling can be deliberate as part of the function of the circuit, or it may be undesirable, for instance due to coupling to stray fields. For example, energy is transferred from a power ...

  6. 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.

    Figure 12. Hybrid ring coupler in planar format. The hybrid ring coupler, also called the rat-race coupler, is a four-port 3 dB directional coupler consisting of a 3λ/2 ring of transmission line with four lines at the intervals shown in figure 12. Power input at port 1 splits and travels both ways round the ring.

  8. Transformer types - Wikipedia

    en.wikipedia.org/wiki/Transformer_types

    Laminated core transformer. This is the most common type of transformer, widely used in electric power transmission and appliances to convert mains voltage to low voltage to power electronic devices.

  9. Voltage transformer - Wikipedia

    en.wikipedia.org/wiki/Voltage_transformer

    A capacitor voltage transformer (CVT), is a transformer used in power systems to step down extra high voltage signals and provide a low voltage signal to the actual VT (voltage transformer) used for operating metering/protective relays due to a lower cost than an electromagnetic PT. The circuit diagram for a simple capacitor voltage transformer
