What does an AMP measure?

The AMP, or ampere, measures the amount of current flowing in a circuit. Current refers to the flow of electric charge, and the ampere is the standard unit used to quantify this flow. Understanding current is crucial for estheticians, especially when dealing with electrical equipment such as machines used for various skin treatments. By measuring the current, one can ensure that the devices are operating within safe and effective parameters.

Other measurements such as voltage, energy, and resistance pertain to different aspects of electrical concepts. Voltage measures the potential difference in a circuit, total energy addresses consumption over time, and resistance quantifies how much a material opposes the flow of current. Each of these measurements serves its purpose, but for assessing how much current is present in a circuit, the amp is the appropriate unit of measurement.
