Physics Chapter 6: Electricity

Question 1

Permittivity

Answer 1

is a measure of how well a material can store or transmit electric field energy, influencing the strength of the electric field within the material.

Question 2

Any form of matter has a ___________ permittivity than the permittivity of free space

Answer 2

Higher

Question 3

Capacitance formula

Answer 3

C = ε0(A/d)

Question 4

Definition of capacitance

Answer 4

ability of a system to store electric charge per unit of electric potential difference between its conductors

Question 5

permittivity of free space constant (ε0)

Answer 5

9×10-12 F/m

Question 6

Capacitance is measured in

Answer 6

Farads

Question 7

Electric field strength between 2 plates

Answer 7

E =V/d. can be measured either in force per charge (N/C) or volts per m (V/m)

Question 8

Force on a particle in a uniform electric field equation

Answer 8

F = qE

Answer 9

k = coulomb’s constant = 9 X 10 ^9 Nm^2C^-2

Question 10

Coulomb’s constant

Answer 10

9 X 10 ^9 Nm^2C^-2
