MDC Science Electrical Circuits

Terms in this set (32)

atom
tiny particles which make up all matter
attract
to pull or stick together two differently charged objects
electricity
a form of energy which can be transferred from one place to another in a closed circuit
bulb
a system which uses electrical energy to generate light and heat energy
circuit
a complete or partial path through which an electrical current may flow
conductor
material through which energy moves:copper wire is a good conductor of electricity
battery
also known as a dry cell, this uses chemicals to make an electrical charge
electrons
negatively charged particals in an atom
energy
the abilty to do work; various forms exist such as heat, electricity, chemical and light energy
filament
a resistant wire in a bulb with transforms electrical energy into light energy
insulator
a material that does not easily conduct electricity (a nonconductor)
neutron
an uncharged particle in the nucleus of an atom
parallel circuit
a circit that gives electricity more than one path to flow through
polarity
in batteries, the condtion of having positive and negative ends which must be aligned correctly for the batteries to be in series or parallel
proton
a unit of positive charge found in the nucleus of an atom
schematic
a diagram showing how something is put together, for example a wiring diagram
series circuit
a circuit that has only one path for electricity to flow through
switch
a device in an electrical circuit that opens and closes the circuit
symbol
a written sign that represents a part of an electrical circuit in a schematic
terminal
a point which must be touched in order to make a complete circuit
wiring diagram
a drawing using symbols to show how a circuit is put together
heat
a stove is this form of energy
mechanical
riding a bike is what form of energy
chemical
a battery is this form of energy
solar
the sun is this form of energy
electrical
a wall outlet is this form of energy
light
a light bulb is this form of energy
sound
