What does the unit 'AMP' measure in electricity?

The unit 'AMP', short for ampere, measures electrical current, which refers to the flow of electric charge in a circuit. Understanding this concept is critical, especially in advanced esthetic practices where electrical devices are commonly used.

Electrical current is quantified in amperes, with one ampere representing one coulomb of charge moving past a point in a circuit in one second. This makes it a fundamental measurement for ensuring that devices operate safely and effectively, as different equipment may require specific current levels to function correctly.

In contrast, electrical pressure is measured in volts, electrical strength can refer to the intensity of the current, and electrical resistance is measured in ohms. Each of these measurements plays a role in understanding electrical systems, but when it comes to the direct flow of electricity, amplifying current is the key concept linked with the unit AMP. This is essential for anyone working with electrical equipment in esthetics.
