Chpt 17: Electric Potential Flashcards
electric potential
type of potential energy
amt of energy that is required to move an electron or proton from one place to another within an electrical field
symbol for electrical potential
V for volts or voltage
Volt
the term/unit for electric potential
Units for volts/voltage
joules per coulomb (where coulomb is the charge of one electron)
Potential difference
Delta electrical potential (as in delta V for delta volts)
Electrical field
an ‘aura’ or region around a charged that attracts or repels other charges
Capacitor
a device that can store electrical charge (usually involves two equal but opposite conducting plates)
Capacitance
Physical property of capacitors that tells you how much electrical charge they can hold
Condition under which voltage can be related to electrical field
when electrical field is constant
equipotential line
a line that depicts the electrical potential for particles found at a given location within an electrical field
*the electrical potential for all points along an equipotential line are equal, and no work is required to move particles along the line.
equipotential surface
a 3D version of an equipotential line that depicts electric potential for particles found in a given location on a sphere around a charge
How much does an eVolt equal
the voltage for each electron (volts/Coulombs)
