Electricity and Electrical Category 1
This is the movement of electrons from one atom to another along a conductor.
What is electricity?
This unit measures the pressure or force that pushes electric current forward through a conductor.
What is a volt?
This is a material that does not transmit electricity and is also called an insulator.
What is a nonconductor?
This extremely low level of electricity mirrors the body’s natural electrical impulses and can be used for firming, toning, and soothing skin.
What is microcurrent?
This is the distance between successive peaks of electromagnetic waves.
What is wavelength?
This device automatically interrupts a circuit when there is an overload and can be reset without replacement.
What is a circuit breaker?
This type of plug includes a third circular connection for added protection against shock.
What is a three-prong plug?
This type of current is rapid and interrupted, flowing first in one direction and then in the opposite direction.
What is alternating current?
This organization certifies that appliances like blowdryers and curling irons meet safety standards.
What is Underwriters Laboratories, or UL?
This color has the shortest wavelength in the visible spectrum.
What is violet?
This is the proper action to take when disconnecting an appliance from the wall.
What is pulling on the plug, not the cord?
This safety feature completes an electric circuit and carries current safely away, and appliances with this feature offer the most protection.
What is grounding?
This device prevents excessive current from passing through a circuit and melts or blows out when the circuit is overloaded.
What is a fuse?
This device changes alternating current to direct current.
What is a rectifier?
This measurement determines the color temperature of LED light and ranges from 1,000 to 10,000.
What is Kelvin(k)?
This is the negative pole process used to soften and emulsify sebum and blackheads in the follicles.
What is anaphoresis or desincrustation?
This device protects from electrical shock by interrupting a household circuit when there is a leak in the circuit, and it is required in bathrooms and kitchens.
What is a ground fault interrupter, or GFI?
This type of plug has two rectangular connections and is designed to be inserted into an outlet only one way.
What is a two-prong plug?
This pole opens the pores, stimulates the nerves, and increases blood supply.
What is the negative pole, or cathode?
This color has the longest wavelength in the visible spectrum.
What is red?
This unit measures the resistance of an electric current.
What is an ohm?
This portion of natural sunlight is made up of invisible infrared light.
What is 60 percent?
This makes up 65 percent of natural sunlight when you combine infrared and ultraviolet light.
What is invisible light?
This metal-containing substance is found in fluorescent bulbs and makes them dangerous if broken.
What is mercury?
This is the name for all forms of energy or radiation that exist, including radio waves, microwaves, light waves, X-rays, and gamma rays.
What is the electromagnetic spectrum?
