Metallic Character Definition: Metallic character describes the set of chemical properties that are associated with the elements classified as metals in the periodic table. Metallic character depends on the ability of an element to lose its outer valence electrons. Also Known As: metallicity, metal character.
Symbol of a transformer. The turns ratio of a transformer is the ratio of number of windings of each side of the transformer. Sometimes you wish to find out the turns ratio of an unlabeled transform.The transformer turns ration is labeled as follows: 1  n 1 :n 2.easuring Voltage to find ratio Edit. Symbol of a transformer. A transformer converts one AC Voltage to another. So inputing an AC Voltage and measuring the output Voltage will give you the turns ratio.
In an autotransformer, portions of the same winding act as both the primary and secondary sides of the transformer. In contrast, an ordinary transformer has separate primary and secondary windings which are not connected. The winding has at least three taps where electrical connections are made.ecause it requires both fewer windings and a smaller core, an autotransformer for power applications is typically lighter and less costly than a two-winding transformer, up to a voltage ratio of about 3:1; beyond that range, a two-winding transformer is usually more economical.
