Electricity

Question 0

Electric Field

Answer 0

The region around a charged object where the object’s electric force is exerted on other charged objects.

Question 1

Electric Force

Answer 1

The force between charged objects.

Question 2

Static Electricity

Answer 2

A buildup of charges on an object.

Question 3

Conservation of Change

Answer 3

The law that states that charges are neither created nor destroyed.

Question 4

Friction

Answer 4

1. The force that two surfaces exert on each other when they rub against each other. 2. The transfer of electrons from one uncharged object to another uncharged object by rubbing.

Question 5

Conduction

Answer 5

1. The transfer of thermal energy from one particle of matter to another. 2. A method of charging an object by allowing electrons to flow from one object to another object through direct contact.

Question 6

Induction

Answer 6

A method of redistributing the charge on an object by means of the electric field of another object; the objects have no direct contact.

Question 7

Polarization

Answer 7

The process through which electrons are attracted to or repelled by an external electric field, causing the electrons to move within their own atoms.

Question 8

Static Discharge

Answer 8

The loss of static electricity as electric charges transfer from one object to another.

Question 9

Electric current

Answer 9

The continuous flow of electric charges through a material.

Question 10

Electric Circuit

Answer 10

A complete, unbroken path through which electric charges can flow.

Question 11

Conductor

Answer 11

1. A material that conducts heat well. 2. A material that allows electric charges to flow.

Question 12

Insulators

Answer 12

Are materials such as rubber, that do not allow charges to flow.

Question 13

Voltage

Answer 13

The difference in electrical potential energy per charge between two places in a circuit.

Question 14

Ohm’s law

Answer 14

The difference in electrical potential energy per charge between two places in a circuit.

Question 15

Series Circuit

Answer 15

An electric circuit in which all parts are connected one after another along one path.

Question 16

Parallel Circuits

Answer 16

Different parts of the circuit are on separate branches.

Question 17

Power

Answer 17

The rate at which energy is transformed from one form to another is known as power.

Question 18

Short Circuit

Answer 18

A connection that allows current to take the path of least resistance.

Question 19

Third Prong

Answer 19

The round prong of a plug that connects any metal pieces in an appliance to the safety grounding wire of a building.

Question 20

Grounded

Answer 20

Allowing charges to flow directly from the circuit into the building’s ground wire and then into Earth in the event of a short circuit.

Question 21

Fuses

Answer 21

Are devices that melt if they get to hot.

Question 22

Circuit Breakers

Answer 22

Are switches that will blend away from circuits as they heat up.
