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.
An ac voltmeter is connected to the secondary to measure the output voltage. To make the calculation of the turns ratio easy, the input voltage is increased until the voltage on the secondary reads 1 volt.With the secondary reading 1 volt, measure the input voltage to the primary.ince the voltage on the secondary is set to 1 volt, the voltage measured on the primary will be the turns ratio. For example, if the voltage on the primary measures 25 volts, the turns ratio is 25:1 as illustrated in figure 2 below. Note: An auto-transformer does not provide isolation from the ac line.
