Free Electricty

Question 1

Electric Field

Answer 1

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

Question 2

Static electricity

Answer 2

The buildup of charges on an object

Question 3

Conservation of charge

Answer 3

Charges are neither created nor destroyed

Question 4

Friction

Answer 4

Is the transfer of electrons from one uncharged object to another by rubbing the objects together

Question 5

Conduction

Answer 5

Is the transfer of electrons from one to another by 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

Is the continuous flow of electric charges through a material

Question 10

Electric circuit

Answer 10

A complete, unbroken path that charges can flow through

Question 11

Conductor

Answer 11

Is a material through which charges can flow easily

Question 12

Insulators

Answer 12

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

Question 13

Voltage

Answer 13

Is the difference in electric potential energy per charge between two points in a circuit

Question 14

Resistance

Answer 14

Is the measure of how difficult it is for charges to flow through an object

Question 15

Ohm’s Law

Answer 15

Says the resistance in a circuit is equal to voltage divided by current

Question 16

Series circuit

Answer 16

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

Question 17

Parallel Circuit

Answer 17

An electric circuit in which different parts of the circuit are on separate branches

Question 18

Power

Answer 18

The rate at which one form of energy is transformed into another

Question 19

Short Circuit

Answer 19

Is a connection that allows current to take the path of least resistance

Question 20

Third Prong

Answer 20

You may have seen on electrical plugs connects the metal parts of appliances to the safety grounding wire of a building

Question 21

Grounded

Answer 21

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 22

Fuses

Answer 22

Are devices that melt if they get too hot

Question 23

Circuit breakers

Answer 23

Are switches that will bend away from circuits as they help us

Question 24

Electric Force

Answer 24

The force between charged objects
