What is another name for an AC generator?

An AC generator is commonly referred to as an alternator. This term is utilized because an alternator produces alternating current (AC) through electromagnetic induction. The fundamental operation involves rotating a coil within a magnetic field, which induces an electrical current that alternates direction, hence the name "alternator."

The other terms have different specific meanings in the context of electrical and electronic devices. A converter typically refers to a device that changes electrical energy from one form to another, such as converting AC to DC. An inverter, on the other hand, specifically converts DC into AC. A transducer refers to a device that converts one form of energy into another, which can apply to various contexts, including sound to electrical signals or vice versa. Understanding these distinctions clarifies why the term alternator is the correct choice for an AC generator.
