whereas negative charges move in the opposite direction
b. Negative charges move in the direction of the electric field,
whereas positive charges move in the opposite direction
c. Both positive and negative charges move in the direction of
the electric field

direction of the electric field
e. It depends on...
What is the relationship between electric field and electric
potential?
How do we create a potential difference?
I'm trying to understand the concept, this is not a
homework question. Please answer as simple as
possible.
Pre-Lab Questions
1. How are electric potential and electric field
similar? How are they different?
2. Draw the equipotential lines for a single, positive,
charge.
3. If you were to walk on an equipotential line, how
would your electric potential change over time?
4. What does it mean when equipotential lines are
closer together? What does it mean when they are farther
apart?
5. What direction do electric fields travel?
A wire carrying a 30 A current pass between two strong bar
magnets and experiences a 2.16 N force on the 4.00 cm of wire in
the field.
(i) Show the direction of the force in the diagram.
(ii)What is the strength of the magnetic field?
1) Coulomb's Law certainly states that electric forces only
exist between electric charges. A truly neutral particle, like a
neutron, never experiences an electric force. But can an object
that has zero net charge ever experience an electric force? If so,
give a concrete example. If not, explain why
2) A capacitor is literally an open circuit: it is two
conductors separated by an insulator. If you just cut a wire,
technically the two cut ends separated by the air...
Design an experiment to find the relationship between the
electric force between the two spheres and the distance between
them. In the space below, describe your experiment, including:
What quantity did you vary?
What quantities did you hold constant?
What quantity did you measure?
Which quantities did you plot on your graph, and on which
axes?
Which Curve Fit gives the best fit for the data?
Describe your process and the relationship you found. In
particular, note where the data...
