One kilowatt-hour will power a television for three hours, run a 100-watt bulb for twelve hours, and keep an electric clock ticking for three months.

and the
2 Types
of Electric Current
Is a constant,
even-flowing current that travels in
one direction only and is produced by
chemical means.
is a rapid and interrupted current, flowing first in one direction and then in the opposite direction; it is produced by mechanical means and changes directions 60 times per second.

prevents excessive current from passing through a circuit. it is designed to blow out or melt when the wire becomes too hot from overloading the circuit with too much current
is a switch that automatically interrupts or shuts off an electric circuit at the first indication of an overload
completes an electric circuit and carries the current safely away.

(named after Luigi Galvani) constant and direct current that provide services like Iontophoresis, Cataphoresis, Anaphoresis, and Desincrustation.
extremely low level of electricity that mirrors the body’s natural electrical impulses.
(named after Nikola Tesla) also known as violet ray, is a thermal or heat-producing current with a high rate of oscillation or vibration that is commonly used for scalp and facial treatments.

and its majestic qualities
makes up 35% of what natural sunlight lets us see
ultraviolet (UV) short wavelength (high energy) 3 types, UVA, UVB, UVC and infrared … longer wavelengths, penetrates more deeply, has less energy, and produces more heat than visible light.
Catalysts are substances that speed up chemical reactions. Some catalysts use heat as an energy source while others use light. Whatever the energy source, catalysts absorb energy like a battery. At the appropriate time, they pass this energy to the initiator and the reaction begins.
also known as phototherapy, is the application of light rays to the skin for the treatment of wrinkles, capillaries, pigmentation, or hair removal.
an acronym for
Light Amplification Stimulation Emission of Radiation;
it is a medical device that uses electromagnetic radiation for hair removal and skin treatments
Light-Emitting Diode:
a medical device used to reduce acne, increase skin circulation, and improve the collagen content in the skin.
a medical device that uses multiple colors and wavelengths (broad spectrum) of focused light to treat spider veins, hyperpigmentation, rosacea and redness, wrinkles, enlarged hair follicles and pores, and excessive hair.
