Front 1

STATIC ELECTRICITY IS CAUSED WHEN...

Back 1

BUILDUP OF OPPOSITE ELECTRICAL CHARGERS

Front 2

STATIC ELECTRICITY OCCURS PLANNED OR RANDOMLY?

Back 2

RANDOMLY

Front 3

WHAT DOES STATIC MEAN?

Back 3

NOT MOVING, STATIONARY

Front 4

STATIC ELECTRICITY- OBJECTS WITH EVEN AMOUNT OF POSITIVE AND NEGATIVE CHARGES...

Back 4

NEUTRAL

Front 5

STATIC ELECTRICITY - OBJECTS WITH MORE ELECTRONS THEN PROTONS IS...

Back 5

NEGATIVELY CHARGED

Front 6

STATIC ELECTRICITY - OBJECTS WITH MORE PROTONS THEN ELECTRONS IS...

Back 6

POSITIVELY CHARGED

Front 7

LAW OF STATIC CHARGES (3)

Back 7

1. OPPOSITE CHARGES ATTRACT
2. LIKE CHARGES REPEL
3. CHARGED OBJECTS ATTRACT NEUTRAL OBJECTS

Front 8

SERIES CIRCUIT IS?
WHAT HAPPENS TO THE BULBS?

Back 8

ONE PATH OF ELECTRON FLOW.
BULBS SHARE SAME VOLTAGE THEREFORE WHEN ONE BURNS OUT THE OTHER WILL TOO.

**SECOND BULB ALWAYS DIMMER

Front 9

PARALLEL CIRCUIT IS?
WHAT HAPPENS TO THE BULBS?

Back 9

MANY PATHS OF ELECTRON FLOW.
BULBS ARE SAME BRIGHTNESS.
VOLTAGE ISN'T SHARED BETWEEN BULBS.
IF ONE BULB BURNS OUT, THE OTHER STILL STAYS LIGHTED.

Front 10

CONDUCTORS

Back 10

ALLOW FOR MOVEMENT OF ELECTRICITY

INSULATORS

Back 11

APPOSE MOVEMENT OF ELECTRICITY

Front 12

RESISTORS

Back 12

ALLOW SOME FLOW OF ELECTRICITY

Front 13

SEMICONDUCTORS

Back 13

CONDUCT WELL IN HIGH TEMPERATURES.
INSULATE WELL AT LOW TEMPERATURES.

Front 14

SUPERCONDUCTORS

Back 14

NO RESISTANCE, CONDUCT PERFECLY.

Front 15

COULOMBS

Back 15

CHARGE IS MEASURED IN COULOMBS
CHARGE IS TRANSFERRED BY STEADY CURRENT OF ONE AMP IN 1 SECOND

Front 16

Front 21

WET CELLS
USED IN WHAT SOURCE?

Back 21

LIQUID ELECTROLYTES
USED IN VEHICLES
(CHEAPER TO MAKE THEN DRY CELLS)

Front 22

DRY CELLS
USED IN WHAT SOURCE?

Back 22

PASTE ELECTROLYTES
USED IN FLASHLIGHTS (AND OTHER SIMULAR DEVICES)

Front 23

SECONDARY CELL

USED FOR?

Back 23

RECHARGABLE CELL

USED TO START CARS, USED TO OPERATE PORTABLE ELECTRONICS. EX. MP3, IPODS, LAPTOPS, PHONES, ETC.

Front 24

PRIMARY CELL
WHAT DO THEY MAKE?
WHAT 2 CELLS ARE IN THIS CATEGORY?

Back 24

NON-RECHARGABLE CELL
WET AND DRY CELLS ARE THESE
MAKE BATTERY (2 CELLS COMBINED DO)

Front 25

ELECTROLYTE

Back 25

PASTE OR LIQUID THAT CONDUCTS ELECTRICITY

CONTAINS CHEMICALS THAT FORM IONS

Front 26

OHMS LAW:

Back 26

I = V over R

Front 27

WHEN WANTING TO TURN WATTS INTO KILLAWATTS, WHAT IS DONE TO DECIMAL?

Back 27

MOVE TO LEFT 3 SPACES

Front 28

WHEN WANTING TO TURN WATTS INTO MEGAWATTS, WHAT IS DONE TO DECIMAL?
