electric Potential and Electric Energy

The electric field lines between two oppositely charge plates are mostly...

• parallel

• curved

• 0

• repelling

• drawn from low potential to high potential

If an electron moves from one charged plate to another in which there is a difference of 1000V then it

• 1 eV

• 1.6 x 10^-16 dV

• 1 keV

• 1.6 x 10^19 J

• 1000 keV

If an electron moves from a positive plate to a negative plate then it has gained...

• KE

• PE

• speed

• charge

• voltage

If a proton is moved from a positive plate to a negative plate then it moves to the plate with....

• lower electric potential (V)

• higher electric potential (V)

• 0 V

The ground is often taken to be...

• postive

• negative

• 0 V

• a capacitor

Which is not true: Equipotential lines......

• are always continuous and never end

• connect the path charge q spontaneously moves toward

• connect points where voltage is zero

• connect points where no work is done to move a charge q

• are perpendicular to E field lines

How much charge a capacitor can obtain for a set voltage is determined by:

• the area of the dielectric

• the volume of the capacitor

• the number of times it is rolled

• the thickness and type of dielectric and the area of the conducting plates

• the permitivity of free space times the distance of the conducting plate separation

Electric potential difference is measured in:

• V

• C

• F

• N/C

• V or J/C

What is the name of the insulator that is between the plates of a capacitor?

• polyethylene

• dielectric

• cabela

• permitivity of free space

• conductor

It takes 8.0 J of energy to move a +3.0 x 10^-3 C charge from one charged plate A to another charged plate B. Which plate has the higher electric potential?

• A

• B

• not enough information

• both plates have same electric potential
