Although the underlying physics of the transformer, mainly Faraday's law of induction, had been known since the 1830s, transformers became viable only after the introduction of Gaulard and Gibbs's transformer design in 1883. The breakthrough was to build an iron transformer core which could act as a magnetic circuit.
Other Transformers characters that came from the Diaclone line included the Dinobots, Insecticons (from the enemy Waruder toys), the Jumpstarters, the mail-order exclusive Powerdashers and Omnibots, the Decepticon planes (originally from two "JetRobo" toys, produced in the colors of future Decepticons Starscream and Thundercracker) and the ...
The circuit works due to positive feedback through the transformer and involves two times—the time T closed when the switch is closed, and the time T open when the switch is open. The following abbreviations are used in the analysis: t, time, a variable; T closed: instant at the end of the closed cycle, beginning of open cycle.
A circuit where rectifier devices are externally controlled to change AC to current flowing in one direction. actuator An end device of a control system, that manipulates a physical variable such as a valve opening or position of a machine part. adaptive control A control strategy where parameters are adjusted as the controlled process changes.
Steinmetz's work revolutionized AC circuit theory and analysis, which had been carried out using complicated, time-consuming calculus-based methods. In the groundbreaking paper, "Complex Quantities and Their Use in Electrical Engineering", presented at a July 1893 meeting published in the American Institute of Electrical Engineers (AIEE ...
Symbolic circuit analysis is a formal technique of circuit analysis to calculate the behaviour or characteristic of an electric/electronic circuit with the independent variables (time or frequency), the dependent variables (voltages and currents), and (some or all of) the circuit elements represented by symbols.

Simulation-based methods for time-based network analysis solve a circuit that is posed as an initial value problem (IVP). That is, the values of the components with memories (for example, the voltages on capacitors and currents through inductors) are given at an initial point of time t 0 , and the analysis is done for the time t 0 ≤ t ≤ t f ...
His work in the electrification of Great Barrington's Main Street was named an IEEE Milestone. [ 4 ] Agreeing that the AC system had arrived, Westinghouse further tested the system in summer 1886 in Pittsburgh; it transmitted over a distance of 3 miles, and used an alternator designed by Stanley to replace the Siemens model, which regulated ...
