Science

Front 1

Electron

Back 1

Negatively charged, the outer part of the atom, always in motion

Front 2

Neutron

Back 2

Neutral, stays in the neucleus and keeps the protons in the nucleus

Front 3

Proton

Back 3

positively charged, stays in the nucleus, cannot move from one object to another

Front 4

Positively Charged Object

Back 4

more protons than electrons, the electrons have been moved to a different object

Front 5

Negatively Charged Object

Back 5

An object, which has more electrons in it than protons

Front 6

Static Electricity

Back 6

A stationary electric charge, created with friction

Front 7

Current Electricity

Back 7

Conduction or a electric current caused by continuous movement of charged particles

Front 8

Kinetic Energy

Back 8

Energy in the form of motion

Front 9

St. Elmo's Fire

Back 9

A step leader coming up from an object (like a ships mast), but doesnt connect with lightning. In the olden days they thought it was a good sign from the gods

Front 10

Thales

Back 10

First scientist to study electricity, played with amber and figured some this out about electron

Front 11

Greek word for amber

Back 11

Elektron

Front 12

Static cling

Back 12

When protons and electrons separate and the opposite forces attract

Front 13

Red Sprite and Blue Jet

Back 13

Both a form of lightning that goes up from the clouds instead of downwards

Front 14

Cell

Back 14

A device which converts chemical energy to electrical energy

Front 15

Electrode

Back 15

the conductors in a cell (the metal ends)

Front 16

Electrolyte

Back 16

The liquid or paste in a cell

Front 17

Battery

Back 17

Two or more cells joined together

Front 18

Which was will the compass point

Back 18

Geographical North is magnetic south. A compass always points south. If a compass is held between the north side of a magnet and a south side, the compass would point to the south

Front 19

Efficiency

Back 19

Output over input

Front 20

Iron, nickel, cobalt

Back 20

These are the only things which stick to magnets and the only things that you can make permanent magnet out of because th electrons all travel in the same direction

Front 21

Dr. Galvani

Back 21

Experimented with frog legs, and though he could temporarily bring people back to life with a shock

Front 22

Volta

Back 22

Hated Galvani and used his observations of the frogs to make the first cell

Front 23

Oerstead

Back 23

Discovered that a wire with electricity running through it had a magnetic field running through it

Front 24

Electromagnet

Back 24

It occurs when you wrap a wire around a metal and attach each end of the wire to a cell and run the electricity through the wire, which is around the metal, creating a magnet

Front 25

Different ways to make electricity

Back 25

Geothermal, solar or photoelectric, hydro, wind, thermocouple, nuclear, and piezoelectric effect

Front 26

Parts of an electric motor

Back 26

Brush, electromagnet, split ring commutator, insulating gap, armature, magnets, brush

Front 27

Circuit

Back 27

can be serious or parallel and includes a source, control, conductor and load

Front 28

Open circuit

Back 28

When the switch or control is open and electricity cannot move

Front 29

Closed Ciruit

Back 29

When the switch or control is down and the electricity can move through the circuit

Front 30

Short Circuit

Back 30

When the electricity goes around the load and goes really fast; this is very dangerous

Front 31

Series Circuit

Back 31

The electricity has to pass through every load, if one goes out, they all go out

Front 32

Parallel circuit

Back 32

The electricity goes through the different loads seperatly and there can be different switches for different things

Front 33

Circuit Breaker

Back 33

Uses a bimetallic strip to automatically turn off the electricity if it is short circuiting and going to fast and getting to hot

Front 34

Fuse

Back 34

Thin wire incased in glass that melts if it gets to hot and shuts off the circuit

Front 35

Incandescent light bulbs

Back 35

A light bulb with a thin wire, which creates a lot of resistence with electricity and glows as a result

Front 36

Filament

Back 36

Thin wire inside an incandescent light bulb

Front 37

Florescent light

Back 37

Electricity runs through the filament and transfers into the gasses, making the excited and they glow

Front 38

Hot wires:

Back 38

carry electricity to the load

Front 39

Neutral wires

Back 39

do not carry electricity

Front 40

AC

Back 40

Alternating Current, current moves back and forth

Front 41

DC

Back 41

Direct Current, current goes directly to your house and the appliance being used

Front 42

Load/resistor

Back 42

This is what needs th eenergy, or wher eis energy is being transfered to. Ex. lightbulb, t.v.

Front 43

Control

Back 43

What you use to control whether the electricity is running in a complete circuit or is turned off

Front 44

Conductor

Back 44

This would be the wire that the electricity uses to get to the load

Front 45

Source

Back 45

This would be the cell or generator, it produces or procide the circuit with electricity
