Question 9

Static Electricity

Answer 9

Buildup of charge on an object.

Question 10

Field Lines

Answer 10

Represent direction of electric fields.

Question 11

Amperes

Answer 11

Amount of charge passing through a given point per second.

Question 12

Circuit

Answer 12

A path that runs in a loop.

Question 13

Voltage

Answer 13

Difference in electric potential energies.

Question 14

Law of Conservation of Charge

Answer 14

Charge cannot be created or destroyed.

Question 15

Conduction

Answer 15

Movement of charge by direct contact between 2 objects.

Question 16

Friction

Answer 16

2 objects rub against each other, and electrons move from one object to another object.

Question 17

Induction

Answer 17

Electric field of one object repels electrons of another object, causing second object to have a buildup of charge on its opposite side.

Question 18

Polarization

Answer 18

Electric field of one object repels electrons of other object, causing second object to have a buildup of charge by having the electrons move to the opposite side of their atoms.

Question 19

Magnet

Answer 19

Matter that attracts iron and other materials containing iron.

Question 20

Magnetism

Answer 20

Attraction or repulsion between magnetic materials.

Question 21

Magnetic Force

Answer 21

Push or Pull between a magnet and and object or another magnet.

Question 22

Magnetic Poles

Answer 22

Ends of a magnet where the magnetic force is the strongest.

Question 23

Magnetic Field

Answer 23

Area of magnetic force surrounding a magnet.

Question 24

Solar Wind

Answer 24

Constant stream of particles flowing from the sun to Earth.

Question 25

Electromagnetism

Answer 25

Relationship between electricity and magnetism.

Question 26

Galavanometer

Answer 29

Device that measures small currents.

Question 30

Electric Motor

Answer 30

Device that uses electric current to turn an axle.

Question 31

Electromagnetic Induction

Answer 31

Process of generating an electric current from the motion of a conductor through a magnetic field.

Question 32

Transformer

Answer 32

Device that increases or decreases voltage using 2 separate coils of insulated wire that are wrapped around an iron coil.

Question 33

Electric Generator

Answer 33

Motion of a coil of wire through a magnetic field produces a current, and mechanical energy is transformed into electrical energy.

Question 34

Primary Coil

Answer 34

Coil current flows through first.

Question 35

Secondary Coil

Answer 35

Coil current flows through after flowing through the primary coil and the iron core.

Question 36

Direct Current

Answer 36

Charge only flows in one direction.

Question 37

Alternating Current

Answer 37

Constantly reversing current.
