Card Set Information
Electric Potential, Electric Potential Energy, Work by Electricity
What is The Electric Potential energy?
U = kQ
What does electric potential stand for?
What is Electrostatic Potential?
What is the work done ON a charge?
How do you find the total potential of a point between two charges?
V = kQ/R + kQ/R …. Sum of Volts, each their own R distance away from point.
What is potential difference?
In a constant electric field what is voltage equal to?
V = Ed
What charge has a higher potential?
What charge has a lower potential?
What is the work done on a charge equal to?
W = Q∆V = Fd = ∆KE
How do you determine the sign of Work?
Observing the direction of motion in comparison to the electric field.
When motion opposes field, positive work. (Up Stairs)
When motion moves along field, negative work. (Gravity)
When the motion of a charge opposes the field what is the sign of the work?
In what direction does a charge doing negative work travel?
Along the field lines.
How do you calculate the total electrostatic potential ENERGY?
/r And just keep summing them, keeping track of their parts.
What is the work done? In both KE and delta V
What is electrostatic potential (voltage) in a uniform electric field?
What is the electric potential of a point charge or sphere?
V = kQ/r
What is the net/total electric potential?
What is the electrostatic potential energy?
Does electrostatic potential energy have a sign?
Yes, from the contributing charges.
