Electric Potential and Energy
What is the electric potential at a point in space if a charge of 7.3 × 10-17 coulombs at that point has a potential energy of 6.4 × 10-17 joules?
0.88 volts
A charge of +1.4 × 106 coulombs moves from point A to B. What is the potential difference between the two points if the work done on the charge is +3.4 × 107 joules?
24 volts
A charge of +3.1 × 10-16 coulombs is moved between two points, resulting in a potential difference of +15 volts. What is the magnitude of the work done on that charge?
4.7 × 10-15 joules
Which statement is true about a positive charge freely moving from rest under the influence of an electric potential?
A positive charge always moves from a higher potential to a lower potential.
What happens to the potential energy of a stationary charge when it begins to move freely from one point to another under the influence of an electric field?
It decreases.
A charge moves from point A to point B in an electric field. What is true about the potential energy of the charge?
It is dependent on the value of the charge and its position
If the voltage across two oppositely charged parallel plates is kept constant, what happens to the relationship between the electric field and the distance between the two plates?
The electric field is inversely proportional to the distance.
