Ideal Transformers
A transformer consists of several coils wound on a common core that usually consists of laminated iron (to reduce eddy-current loss). Transformers are usually used to adjust the values of ac voltages. A transformer can step up or step down … Read more

Transformers
A transformer is a device used to change the relative amplitudes of voltages and current in an AC circuit. A transformer consists of primary and secondary windings whose magnetic fluxes are linked by a ferromagnetic core. The principle of working … Read more
