Transformer. An O-core transformer consisting of two coils of copper wire wrapped around a magnetic core. In electrical engineering, a transformer is a passive component that transfers electrical energy from one electrical circuit to another circuit, or multiple circuits. A varying current in any coil of the transformer produces a varying ...

V. VI. v. t. e. Very high frequency ( VHF) is the ITU designation [1] 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 ...

The RF performance of these configurations is similar, however. The relationship of voltage and current between primary and secondary windings, as well as the terminating impedances, are given by the following equations. V = N V and I = I. 2 1 2 1 ÷ N, where N is the turns ratio. 2 Since Z 2 = V 2 ÷ I 2 and Z 1 = V 1 ÷ I 1 , Z 2 = N Z 1 .
