We're asked to select all statements that describe equipotentials in the vicinity of the parallel plate configuration.
00:08
So when the electric field is zero, all electrical field lines are parallel to the y -axis.
00:15
This is true because remember, our parallel plate capacitors oriented as this being the y -axis here.
00:24
And so if it's parallel, then we have some lines.
00:30
They have, when the electric field is zero, then it will be, when the electric field is zero, then all the electrical field lines are parallel to the y -axis, because this represents zero, zero voltage, essentially.
00:52
So when the electrical field is non, it's when the electrical fields are non -zero, so they're non -zero, the electrical field lines are parallel to the y -axis.
01:02
So when they are non -zero, the electrical field lines are parallel to the y -axis.
01:09
Oh, this is the, sorry, this is the z -axis, and this is the y -axis.
01:13
So when it's non -zero, we're going to have some amount of electric field still, so we'll have some potential, so it has to be parallel to the y -axis, because we're going to, we need, and this shows that we have some potential...
