What unit is used to measure electrical resistance?

Volt
Ohm
Amp
Circuit

The correct answer is: Ohm

The unit used to measure electrical resistance is the ohm. This measurement quantifies how much a material opposes the flow of electric current. In practical applications, understanding resistance is crucial for estheticians, especially when working with electrical devices such as microdermabrasion machines or LED light therapy equipment. Resistance is a fundamental concept in the field of electricity and electronics, described in Ohm's Law, which states that the current flowing through a conductor between two points is directly proportional to the voltage across the two points and inversely proportional to the resistance in that path. Therefore, when considering safe and effective usage of electrical tools in esthetics, an understanding of ohms can help practitioners ensure they are operating devices within safe parameters.
