Chapt 11 Electric Potential

Question 1

Potential of an object located between charged plates

Answer 1

V : E x (distance from the negative plate to the object)

Question 2

A point charge and need potential

Answer 2

V : kq/r

Question 3

Electric potential energy

Answer 3

Ue : qV

Question 4

Work of electricity

Answer 4

W = K difference = Ue difference = -q(V difference)

Question 5

Acceleration of charge through a potential difference

Answer 5

(1/2)mv^2 = q(potential difference)

Question 6

Capacitance of plates

Answer 6

C = (EoA)/d

Question 7

Eo

Answer 7

Permittivity of free space

8.85 x 10^-12 C^2m^2/N

Question 8

Potential difference between charged plates

Answer 8

V : E x (distance between plates)

Question 9

Charge in capacitor

Answer 9

Q = CV

Question 10

Energy of a capacitor

Answer 10

Uc = (1/2)QV
