What is an Electric Generator?

An electric generator, also known as a dynamo, is a device that converts mechanical energy into electrical energy. It works on the principle of electromagnetic induction, where a magnetic field is generated by a rotating coil or magnet, inducing an electric current in the coil. Electric generators are used in a wide range of applications, from power plants to portable devices, and are a crucial component in the generation and distribution of electrical energy.

Analyzing the Options

Now, let's analyze the options provided to determine which one is another name for an electric generator.

A. Flux Capacitor

A flux capacitor is a fictional device that appears in the Back to the Future movie trilogy. It is a component of the DeLorean time machine and is responsible for generating the 1.21 gigawatts of electricity needed to power the time-traveling vehicle. While the concept of a flux capacitor is intriguing, it is not a real-world device and is not related to electric generators.

B. Transformer

A transformer is an electrical device that transfers electrical energy from one circuit to another through electromagnetic induction. While transformers are used in conjunction with electric generators to step up or step down voltage levels, they are not another name for an electric generator.
