Question 1

Capacitor

Answer 1

A device use to store charge in a circuit

Question 2

Electric field

Answer 2

• A force field that fills the space around very electric charge or group of charges
• measured in N/C

Question 3

electric field lines

Answer 3

vectors pointed in the directions that a test charge would accelerate if placed upon the line

Question 4

electric potential

Answer 4

electric potential energy per coulomb at a location in a electric field
SI unit: volts
volts = Joules/Coulomb

Question 5

Electric potential energy

Answer 5

the energy the charge now possesses by virtue of its location
PE to KE

Question 6

electric shielding

Answer 6

the free charges in a conducting surface will arrange themselves on the surface of the conductor so all field contributions inside cancel

Question 7

lines of force

Answer 7

lines or vectors used to indicate the direction of a field at various points in space

Question 8

Van de Graaff generation

Answer 8

a lab device for building up high voltage

Question 9

volt

Answer 9

• the si unit of electric potential

- 1 volt is the electrical potential different across which one coulomb of charge gains or loses one joule of engery
