New cards

capacitance

the amount of charge that can be stored at a given voltage by a capacitor

2
New cards

capaticance is measured in

  • farads (F)

  • coulombs per volt (C/V)

3
New cards

electric field

  • indicates the force that would act on a unit positive test charge if placed at that location

  • exists at every point in space

  • force per unit charge

4
New cards

electric field is measured in

  • volts per meter (V/m)

  • newtons per coulomb (N/C)

5
New cards

current

the flow of charged particles

6
New cards

current is measured in

  • ampere (A)

  • coulombs per second (C/s)

7
New cards

power

  • the amount of energy transferred or converted per unit time

  • a measure of the rate at which work is done

8
New cards

power is measured in

  • watts (W)

  • joules per second (J/s)

9
New cards

resistance

a measure of the opposition to the flow of current

10
New cards

resistance is measured in

  • volts per ampere (V/A)

11
New cards

electric potential energy

the energy stored in a configuration of charged objects

12
New cards

potential energy

the energy of an object or system due to the body’s position relative to other objects, or the configuration of its particles

13
New cards

potential energy is measured in

joules (J)

14
New cards

electric potential/voltage

  • the amount of work/energy needed per unit of electric charge to move the charge from a reference point to a specific point in an electric field

  • the difference in potential energy per unit charge between two locations in an electric field

  • field x distance

15
New cards

electric potential/voltage is measured in

  • volts (V)

  • joules per coulomb (J/C)

16
New cards

resistivity

describes the extent to which a material opposes the flow of electric current through it

17
New cards

time constant

the time taken by a capacitor to be charged to 63.2% of its maximum value theough a resistor connected to it in series

18
New cards

magnetic field

a region around a magnetic material, amoving electric charge, or a changing electric field within which the force of magnetism acts

19
New cards

magnetic field is measured in

  • tesla (T)

  • weber per square meter (Wb/m²)

20
New cards

emf (electromotive force)

  • not a force

  • the energy transfer per unit of electric charge

  • voltage that drives electric current

21
New cards

emf (electromotive force) is measured in

  • volts (V)

  • joules per coulomb (J/C)

22
New cards

24
New cards

specific heat

the heat required to raise the temperature of one gram of a substance by one Kelvin or degree Celsius

25
New cards

specific heat is measured in

joules per gram kelvin (J/gK)

26
New cards

index of refraction

  • a measure of how much the path of light is bent, or refracted, when entering a material

  • a measure of how much light slows down when passing through a medium compared to a vacuum

27
New cards

decay constant

the probability per unit time that a radioactive nucleus will decay

28
New cards

work function

the minimum wuantity of energy required to remove an electron to infinity from the surface of a given solid
