basics of electricity Flashcards
the movement of atoms of particles around an atom that creates pure energy
electricity
– is the flow of electricity along along a conductor
electric current
a - is any substance that conducts electricity
conductor
an - or - is a subsgtance that does not easily transmit electricity
insulator or nonconductor
a — is the path of electrical currents moving from the generating source
complete electrical circuit
– is a constant, even-flowing current that travels in one direction only
direct current
– is a rapid and interrupted current, flowing first in one direction and then in the opposite direction
alternating current
the unit that measures the pressure of force that pushes the flow of electrons through a conductor
volt
the unit that measures the strength of an electric current
amp
is one thousandth of an ampere
milliampere
is a unit that measures the resistance of an electric current
ohm
measurement of how much electric energy is being in 1 second
watt
is 1,000. the electricity in your house is measured in kilowatts per hours (kwh)
kilowatt
an action or substance that speeds up a reaction, and is used to make reactions happen more quickly
catalyst
visible light that has a short wavelength, is less penetrating than visible light, causes chemical reactions to happen quicker, producing less heat than visible light and kills germs
ultraviolet light
