Question

What will happen to a negatively charged particle placed at rest between points that have electric potentials 0V and 9V? Explain.b)Discuss the meanings of the words “potential,” “potential difference,” and “voltage.” Give examples to help illustrate what you’re talking aboutc)How canthe knowledge of electric potential help us understand the motion of electrically charged particles in electric circuits? Answer in your notebookand on the whiteboard.

Answer 1

Hey there!

a) The electric field is in direction of decreasing value of potential so the electric field here will points towards 0v from 9 v. But the charge on particle is negative so the force will be towards the 9v point. and so the charge will move towards the 9 V point.

b) Electric potential is a location-dependent quantity that expresses the amount of potential energy per unit of charge at a specified location while.the electric potential difference is the difference in electric potential (V) between the final and the initial location when work is done upon a charge to change its potential energy. Electric potential is always a relative quantity because no one can find out absolute potential at a point, so in reality only potential difference exists. We can assume potential at certain point (say at infinity it is zero) only then we are able to define potential at every point.

c) The knowlendge of electric potential helps us in finding the work done on the particle which is used in work energy theorem to find out the chanrge in kinetic energy and other stuff.

Hope this helps!
