Resonant inductive coupling or magnetic phase synchronous coupling[4][5] is a phenomenon with inductive coupling in which the coupling becomes stronger when the "secondary" (load-bearing) side of the loosely coupled coil resonates. [5] A resonant transformer of this type is often used in analog circuitry as a bandpass filter.
Generic block diagram of a wireless power system. Wireless power transfer (WPT; also wireless energy transmission or WET) is the transmission of electrical energy without wires as a physical link. In a wireless power transmission system, an electrically powered transmitter device generates a time-varying electromagnetic field that transmits ...
A neon-sign transformer (NST) is a transformer made for the purpose of powering a neon sign. They convert mains voltage in the range 120-347 V up to high voltages, in the range of 2 to 15 kV. These transformers supply between 18-30 mA; 60 mA on special order. [1] The high-voltage electricity produced is used to excite neon or other gases are ...
There are three primary types of voltage transformers (VT): electromagnetic, capacitor, and optical. The electromagnetic voltage transformer is a wire-wound transformer. The capacitor voltage transformer uses a capacitance potential divider and is used at higher voltages due to a lower cost than an electromagnetic VT.
Launched in the summer of 2002, Transformers: Armada was the first series co-produced between Hasbro and Takara, with the intention of creating a toyline for simultaneous release in both North America and Japan. It was released in Japan six months later in January 2003, where it was known as Transformers: Micron Legend.
The Easy-Bake Oven is a working toy oven introduced in 1963 and manufactured by Kenner and later by Hasbro. [1] [2] The original toy used a pair of ordinary incandescent light bulbs as a heat source; current versions use a true heating element.
According to the FDA press statement, in 2020 the agency conducted a safety assessment of PFAS, leading manufacturers to voluntarily pledge to stop selling food packaging items that contained ...
Electric arc. An electric arc between two nails. An electric arc (or arc discharge) is an electrical breakdown of a gas that produces a prolonged electrical discharge. The current through a normally nonconductive medium such as air produces a plasma, which may produce visible light. An arc discharge is initiated either by thermionic emission or ...
