Final answer:
The component that steps up or steps down voltage in HVAC applications using AC induction is the Transformer, which is based on Faraday's law of induction.
Step-by-step explanation:
The correct answer is option C. Transformer. Transformers work on the principle of electromagnetic induction and are used to step up or step down voltage levels for various applications, including in HVAC systems.
Voltage transformation is essential for efficiently transmitting electrical power over long distances and also for powering certain devices at homes and industries.
They are designed based on Faraday's law of induction, where a changing magnetic field within the transformer's coils induces a voltage across the secondary winding, which can be of greater or lesser value than the voltage across the primary winding, depending on the design of the transformer.
This property is crucial because it allows alternating current (AC) voltages to be adjusted to be either safe for household use or efficient for power transmission.
The correct answer is option C. Transformer.
A transformer is a device that uses the properties of AC induction to step up or step down voltage for particular HVAC applications. It transforms voltages from one value to another using induction. For example, transformers are used to step down high voltages in transmission lines to the 110 to 220 V used in homes.
Transformers are based on Faraday's law of induction, which states that a changing magnetic field induces a voltage in a conductor. This means that transformers cannot be used to change DC voltages because there is no change in primary voltage in DC.
