  2. Induction coil - Wikipedia

    en.wikipedia.org/wiki/Induction_coil

    For this reason, induction coils were called spark coils. An induction coil is traditionally characterised by the length of spark it can produce; a '4 inch' (10 cm) induction coil could produce a 4 inch spark. Until the development of the cathode ray oscilloscope, this was the most reliable measurement of peak voltage of such asymmetric ...

    en.wikipedia.org/wiki/File:Induction_coil...

    The blue trace, i 1 is the current in the coil's primary winding. It is broken periodically by a vibrating contact in the primary circuit called an interrupter. The changes in current create a changing magnetic flux in the coil which induces a high voltage in the secondary coil, v 2 shown in red. The voltage induced in the secondary is ...

  4. Electronic symbol - Wikipedia

    en.wikipedia.org/wiki/Electronic_symbol

    An electronic symbol is a pictogram used to represent various electrical and electronic devices or functions, such as wires, batteries, resistors, and transistors, in a schematic diagram of an electrical or electronic circuit. These symbols are largely standardized internationally today, but may vary from country to country, or engineering ...

    en.wikipedia.org/wiki/Single-line_diagram

    A typical one-line diagram with annotated power flows. Red boxes represent circuit breakers, grey lines represent three-phase bus and interconnecting conductors, the orange circle represents an electric generator, the green spiral is an inductor, and the three overlapping blue circles represent a double-wound transformer with a tertiary winding.

  7. LC circuit - Wikipedia

    en.wikipedia.org/wiki/LC_circuit

    LC circuit (left) consisting of ferrite coil and capacitor used as a tuned circuit in the receiver for a radio clock Output tuned circuit of shortwave radio transmitter LC circuits are used either for generating signals at a particular frequency, or picking out a signal at a particular frequency from a more complex signal; this function is ...

  8. Talk:Induction coil - Wikipedia

    en.wikipedia.org/wiki/Talk:Induction_coil

    File:Induction coil waveforms.svg; File:Induction coil waveforms with capacitor.svg; Primarily, the figures do not show the effects of breakdown. The comments are misleading. The first figure has an odd idealization. Apparently it wants a stray capacitance to explain a limiting peak voltage but then ignores the capacitance for the decay.

  9. Electromagnetic induction - Wikipedia

    en.wikipedia.org/wiki/Electromagnetic_induction

    A diagram of Faraday's iron ring apparatus. Change in the magnetic flux of the left coil induces a current in the right coil. [2] Electromagnetic induction was discovered by Michael Faraday, published in 1831. [3] [4] It was discovered independently by Joseph Henry in 1832. [5] [6]
