Ch. 6 Electricity

Question 0

Electric field

Answer 0

Is a region around a charged objects where the objects.

Question 1

Electric force

Answer 1

The fore between charged objects.

Question 2

Static electricity

Answer 2

In static electricity,charges build up on an object, but they do not flow continuously.

Question 3

Conservation of charged

Answer 3

An object can’t become charged by destroying or creating its own electrons.

Question 4

Friction

Answer 4

Is the transfer of electrons from one uncharged objects to together.

Question 5

Conduction

Answer 5

Is the transfer of electrons from one object to another by direct contact.

Question 6

Induction

Answer 6

The opposite happens if the other object is positively charged

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

Conductors

Answer 10

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

Question 11

Insulators

Answer 11

A material that does not conduct heat well. 2. A material that does not easily allow electric charges to flow.

Question 12

Voltage

Answer 12

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

Question 13

Resistance

Answer 13

The measurement of how difficult it is for charges to flow through an object.

Question 14

Ohm’s law

Answer 14

The law that states that resistance in a circuit is equal to voltage divided by current.

Question 15

Series circuit

Answer 15

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

Question 16

Parallel circuit

Answer 16

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

Question 17

Short circuit

Answer 17

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

Question 18

Third prong

Answer 18

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

Question 19

Grounded

Answer 19

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 20

Fused

Answer 20

A safety device with a thin metal strip that will melt if too much current passes through a circuit.

Question 21

Circuit breakers

Answer 21

A reusable safety switch that breaks the circuit when the current becomes too high.
