Current in electrical systems is measured in which unit?

The measurement of current in electrical systems is expressed in amperes. This unit quantifies the flow of electric charge in a circuit. When a voltage is applied across a conductor, the current represents the movement of electrons through that conductor. Amperes, often shortened to "amps," are fundamental to understanding how electrical systems operate, as they help determine the amount of electricity flowing at any given moment.

In the context of electrical formulas, current (in amperes) is also a critical component of the relationship defined by Ohm's Law, which states that current is equal to voltage divided by resistance. This reinforces the importance of understanding and applying the concept of current in electrical work, troubleshooting, and system design.
