The prefix "equi" means equal.
Now, think about the word "equipotential" and try to deduce its meaning.
I hope all you must have guessed it right!
A surface that has a constant electric potential all over it is called an equipotential surface.
Okay, so here are some interesting and useful facts and observations about equipotential surfaces:
-
No work is required to move a charge from one point to another on an equipotential surface.
-
Near an isolated point charge, the equipotential surface is a sphere.
-
The surface of a charged conductor is always an equipotential surface whatever may be its shape.
-
The electric lines of force are always normal to the equipotential surface.
-
Work is done to move a charge from one equipotential to another equipotential surface.
