  2. 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 .

  3. Snap Circuits - Wikipedia

    en.wikipedia.org/wiki/Snap_Circuits

    An AM radio made from a Snap Circuits kit. Snap Circuits is a line of electronic kits manufactured by Elenco Electronics and aimed at children eight years and older. [1] The kits come in a variety of sizes, and may include capacitors, diodes, electric motors, lamps, LEDs, radios, electromagnets, speakers, resistors, transformers, transistors and voltmeters.

  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. Transformer types - Wikipedia

    en.wikipedia.org/wiki/Transformer_types

    The two cylindrical metal cases fit into octal sockets; each one contains a 1:1 line transformer, the first is rated at 600 ohms, the second is rated at 15,000 ohms. On the far right is a DI unit; its 12:1 transformer (with yellow insulation) changes a high impedance unbalanced input to a low impedance balanced output.

  6. Wilkinson power divider - Wikipedia

    en.wikipedia.org/wiki/Wilkinson_power_divider

    No loss occurs when the signals at ports 2 and 3 are in phase and have equal magnitude. In case of noise input to ports 2 and 3, the noise level at port 1 does not increase, half of the noise power is dissipated in the resistor. By cascading, the input power might be divided to any -number of outputs.

Connectors on this cable would be designated:

  8. Balun - Wikipedia

    en.wikipedia.org/wiki/Balun

    Isolation transformer. In classical transformers, there are two electrically separate windings of wire coils around the transformer's core. The advantage of transformer-type over other types of balun is that the electrically separate windings for input and output allow these baluns to connect circuits whose ground-level voltages are subject to ground loops or are otherwise electrically ...

  9. Isolation transformer - Wikipedia

    en.wikipedia.org/wiki/Isolation_transformer

    An isolation transformer is a transformer used to transfer electrical power from a source of alternating current (AC) power to some equipment or device while isolating the powered device from the power source, usually for safety reasons or to reduce transients and harmonics. [1] Isolation transformers provide galvanic isolation; no conductive ...
