Unit 9

Question 1

Circuit

Answer 1

a loop of conductive material through which electrons flow continuously

Question 2

Conductor

Answer 2

in electricity, a substance capable of transmitting electric charge

Question 3

Current

Answer 3

movement of electric charge; consists of the transfer of millions of individual electric charges from atom to atom

Question 4

Electric Charge

Answer 4

the quantity of unbalanced electricity in an object; a charge is either positive or negative and can be understood as an excess or deficiency of electrons

Question 5

Electric Potential

Answer 5

the difference in electric charge between two points in a circuit, expressed as volts

Question 6

Electricity

Answer 6

the flow of electric charge

Question 7

Field

Answer 7

in physics, a region throughout which a force may be exerted; examples include gravitational, electric, and magnetic fields

Question 8

Insulator

Answer 8

in electricity, a substance capable of inhibiting the transmission of electric charge (one that is a poor conductor of electricity)

Question 9

Magnetism

Answer 9

properties associated with having a magnetic field, particularly the tendency of each pole to attract an opposite pole and repel a like pole

Question 10

Resistance

Answer 10

the quality of a substance that hinders the flow of electrons through it; the ratio of the voltage to the electric current

Question 11

Static Electricity

Answer 11

electric charges that are isolated and motionless and are not being transmitted by a conductor
