    One of the younger Nebulans to binary bond to a Transformer, Haywire is very much of the "act first, think later"-impulsive-teenage mold. In that respect, the relationship between Haywire and his partner Blurr is one where they get on like a house on fire, but also a classic example of the lack of planning in the early stages of Targetmasters ...

    In 1891, Nikola Tesla invented the Tesla coil, an air-cored, dual-tuned resonant transformer for producing very high voltages at high frequency. [79] Audio frequency transformers (" repeating coils ") were used by early experimenters in the development of the telephone .

    There are several types of transformer used in radio frequency (RF) work. Laminated steel is not suitable for RF. Air-core transformer . These are used for high frequency work. The lack of a core means very low inductance. All current excites current and induces secondary voltage which is proportional to the mutual inductance.

    en.wikipedia.org › wiki › Very_high_frequency

    Very high frequency (VHF) is the ITU designation for the range of radio frequency electromagnetic waves (radio waves) from 30 to 300 megahertz (MHz), with corresponding wavelengths of ten meters to one meter. Frequencies immediately below VHF are denoted high frequency (HF), and the next higher frequencies are known as ultra high frequency (UHF).
