- A transformer is a device used for stepping up or stepping down AC voltages.
- A step-up transformer is one for which the output voltage is greater than the input voltage.
- A step-down transformer is one for which the output voltage is less than the input voltage.
- The turns ratio of a transformer is the ratio of the number of turns in the secondary to that of the primary.
Feb 24, 2012 · A transformer is defined as a passive electrical device that transfers electrical energy from one circuit to another through the process of electromagnetic induction. It is most commonly used to increase (‘step up’) or decrease (‘step down’) voltage levels between circuits. Working Principle of Transformer.
Jun 19, 2023 · A power transformer is a static device that transfers electrical energy from one circuit to another without changing the frequency. It works on the principle of electromagnetic induction and can step up or step down the voltage level of an alternating current (AC) supply.
