Here's why:
* FPS is a mechanical system: The FPS system is primarily designed for measurements in mechanics, focusing on units like feet (length), pounds (force), and seconds (time).
* Electric current needs a separate unit: Electric current is a fundamental electrical quantity and requires a specific unit, which is the ampere (A) in the International System of Units (SI).
While you can express current indirectly using FPS units (e.g., by relating it to force and charge), it's not common practice and can lead to confusion.
In summary, there is no specific unit for electric current in the FPS system. The standard unit for electric current is the ampere (A).
