electrical
an electric current that changes direction at regular time intervals
alternating current
the SI unit for electrical current of the rate of electrical flow, abbreviated as A
a negatively charged ion
the smallest part of an element that still remains the characteristics of that element
atom
atoms that give up electrons causing it to be a positive ion
cation
a simple source of electricity with 2 terminals, a positive and negative terminal
battery
closed half of electricity from the negative terminal of a voltage source to a load and then from the load to the positive terminal of the voltage source .
complete circuit
A circuit with some components connected in series and other components connected in parallel.
complex circuit
a low resistance material that allows electricity to easily flow
conductor
for the fundamental unit electrical charge is equal to the charge of 6.241x10^18 electrons and abbreviated as C
coulomb
the flow of electrons and only one direction
direct current
the flow of electrons through a circuit. unit of measure is the ampere
electrical current
a temporary magnet created by a current flowing in a conducting coil
electromagnet
An electric current produced by the presence of a magnet or magnetic field. may also refer to a magnetic field produced by the presence of an electric current.
electromagnetic induction
a negatively charged particle that orbits around the nucleus
electron
the opposition to the flow of Current through a circuit
resistance
a positively charged particle located in the nucleus of an atom
proton
a conductor often a coil of wire used as a circuit component to produce voltage in the presence of a magnetic field or elelectrical current
inductor
an electrically neutral partial located in the nucleus of an atom
neutron
a circuit containing more than one path for a current flow
parallel circuit
a circuit containing only one path for a current to flow
series circuit
a high resistance material that does not permit the flow of electrons. also called non conductor.
insulator
a material able to attract ferromagnetic material and retain a magnetic field
an atom that has the same number of protons but a different number of a neutrons
isotope
the field surrounding a charged object
electrostatic field
