The voltage produced in a transformer is directly proportional to what factor?

The voltage produced in a transformer is directly proportional to the number of turns on the primary and secondary windings. This principle is fundamental to how transformers operate, known as the turns ratio. When alternating current flows through the primary winding, it creates a magnetic field that induces a voltage in the secondary winding. The voltage induced in the secondary winding depends on the ratio of the number of turns in the primary coil to that in the secondary coil.

For instance, if the secondary winding has more turns than the primary winding, the transformer will increase the voltage (step-up transformer). Conversely, if the primary winding has more turns than the secondary, the transformer will decrease the voltage (step-down transformer). This relationship illustrates that as you increase the number of turns in either winding, the voltage output changes proportionally, which directly influences the transformation of voltage levels.

Understanding this concept is crucial for electrical service and maintenance in commercial food equipment, as it ensures that the proper voltage levels are maintained for safe operation.
