Part Five - Electric Fields and Electric Potential Flashcards
What do all charged objects generate?
An Electric Field
What does a great/large number of field lines around a charged point mean?
That the charge is strong
When drawing or looking at electric field lines, the arrows always go from _________ to __________.
Negative; Positive
What does the following description describe? The field lines are evenly spaced and extend from a + plate to - plate.
A positively charged plate next to a negatively charged plate.
What does the following description describe? The field lines extend from a + particle, and point away, into infinity
A single, positively charged particle.
What does the following description describe? The field lines extend from the + particle pointing into the - particle
Two charged particles, one positive and one negative at some interactive distance.
Energy flows from areas of ________ energy to areas of ________ energy.
High; Low
As the distance from the charged particle increases, what happens to electric potential?
It decreases
The strength of an electric field is strongest where?
The closer you are to the center of the source.
Opposite charges _________ one another, and like charges _________.
Attract; Repel
Electric force between two objects _________ as the charge increases, and __________ as distance increases.
Increases; Decreases
What is the difference between electric potential and electric potential energy?
Both are the potential energy stored when charges are out of equilibrium; Electric Potential is the amount of potential energy stored PER charge; Electric Potential is the Voltage
How are potential difference in energy and electric field strength related?
Where you are in the electric field determines the strength. Closer to the source, the stronger and vice versa. So if you have two points at very different locations in the field, their difference in potential energy is going to be greater than if they were in the same part of the field.
