Transformers are rated by their - Output capabilities, Transformer output is measured in - KVA, In a step down transformer - Voltage goes down current goes up, A step down transformer means - Output voltage is less than input voltage, In a step up transformer - Voltage goes up current goes down, A step up transformer means - Output voltage is greater than input voltage, Transformer cores are made from - Laminations, Laminations prevent the formation of - Eddy currents, Eddy currents are - Loops of circulating current induced within conductors, Electromagnetic induction - The process of generating electrical current in a conductor by placing the conductor in a changing magnetic field, Autotransformer have selectable - Voltage outputs, Transformers operate on the principle of - Mutual induction, VP means - Primary voltage, NS means - Number of secondary turns, IP means - Primary current,
