Electrical Concepts
- Galvanic current is a type of constant and direct current (DC) that has a positive and negative pole.
- It produces chemical changes in tissues and body fluids.
- Galvanic current is used in electric facial and scalp treatments.
- The term "modality" refers to the specific currents used in these treatments.
- Ohm (O) is the unit of measurement for electrical resistance to an electric current.
- Polarity refers to the negative or positive pole of an electric current.
Electrical Concepts
- Ohm (Ω) is the unit of electrical resistance to an electric current.
- Volt (V) is a unit of electrical pressure that pushes the flow of electrons forward through a conductor.
