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.
How to select appropriate transformer for 12V LED Strips . Step 1: Calculate the power consumption of the strip you want âWe can calculate each stripâs power by knowing the LED Type and its rated power for each LED. The formula to calculate is Power Consumption = Wattage of each LED*LED QTY of strip Length. For example, for 100cm long SMD3528, 150LED/roll model, itâs 30LED per 100cm, so its power consumption is 30*0.08= 2.4Watt.
