Final answer:
A transformer is used to step up or step down voltage for HVAC applications, ensuring safe and efficient power distribution.
Explanation:
A transformer is the component that utilizes the properties of AC induction to step up or step down voltage for particular HVAC applications. It is essential in changing voltages for power transmission and household use, ensuring safety and efficiency.
Transformers are crucial in power applications, allowing for easy transformation of voltage levels based on the number of turns in the coils, known as N. Step-up transformers increase voltage for long-distance power transmission, while step-down transformers decrease voltage for household appliances.
