Introductio ad principium de Transformer.

TRANSFFERMER Core (vel magnetica Core) et coil, quod habet duas vel plura, de qua flectens ad virtutem copiam vocatur ad primam spiram et reliquum vocatur ad secundarium. Potest mutare ac voltage, current et impedientia. A simplex core TRANSFERMER PRAETEMPTOR est ferrum core de mollis magnetica materia et duas viscera per diversas in ferrum core. Partes ferrum core est ad confirma magneticam coitus inter duas. Ut ad redigendum et Hysteresis Current Damnum in ferro, Core est de picta Silicon ferro laminated laminated; Non est electrica nexu inter duo lites, quae sunt vulnus per insulatas aeris (vel aluminium) filum.

Unum coil coniuncta ad AC potentia copia vocatur primaria coil (vel prima organo) et alterum coil coniuncta electrica appliance vocatur secundarium (vel secundarium). The actual transformer is very complex, there is inevitably copper loss (coil resistance heating), iron loss (core heating) and magnetic leakage (magnetic induction line closed by air), etc., the ideal transformer is established under the conditions of: ignore the leakage flux, ignore the resistance of the primary and secondary coils, ignore the loss of the core, ignore the no-load current (the current in the primary coil secundarium aperto circuitu). Exempli gratia, cum per virtutem transformer est currens ad plenus onus (rated potestas output de secundaribus), quod est propinqua ad specimen transformer situ.
