Module 11 Test

Question 1

the ability of a material to imped the flow of charge

Answer 1

resistance

Question 2

current that flows form the positive side of the battery to the negative side, this is the way current is drawn in circuit diagrams, even though it is wrong

Answer 2

conventional current

Question 3

Electron flow is ___ of the direction of conventional currents

Answer 3

opposite

Question 4

How do you get a lot of energy out of a low voltage?

Answer 4

put a lot of current through it

Question 5

Opposite charges ___ one another

Answer 5

attract

Question 6

The thicker the cord, the ___ the resistance

Answer 6

lower

Question 7

charging an object by allowing it to come into contact with an object that already has an electrical charge

Answer 7

charging by conduction

Question 8

charging an object without direct contact between the object and a charge

Answer 8

charging by induction

Question 9

Force by two magnetic poles that are the same

Answer 9

repulsive

Question 10

a circuit that does not have a complete connection between the two sides of the power source, as a result current does not flow

Answer 10

open circuit

Answer 14

electric current

Question 15

The lower the resistance, the ___ heat will be made

Answer 15

less
