Electric field strength is greatest where the lines are closest together and weakest where lines are furthest apart.
Where is the electric field the strongest?
The relative magnitude of the electric field is proportional to the density of the field lines. Where the field lines are close together the field is strongest; where the field lines are far apart the field is weakest.
How do you find the electric field strength?
The strength of an electric field E at any point may be defined as the electric, or Coulomb, force F exerted per unit positive electric charge q at that point, or simply E = F/q.
Where is magnitude of electric field greatest equipotential lines?
The equipotential lines can be drawn by making them perpendicular to the electric field lines, if those are known. Note that the potential is greatest (most positive) near the positive charge and least (most negative) near the negative charge. Figure 3.
Where on the graph is the magnitude of the electric field the greatest?
The greatest magnitude on the field is near the most positive side of the graph; the 5V side near the positive terminal.
What is a strong electric field?
A strong electric field applied between the sharp-edged exit of the capillary and an external electrode causes charge separation inside the liquid propellant, which is doped with an additive to increase its electric conductivity.
What do you mean by electric field strength?
electric field strength. A measure of the strength of an electric field at a given point in space, equal to the force the field would induce on a unit electric charge at that point. Also called electric field intensity electric intensity.
Is the electric field strength at point A larger than smaller than or equal to the field strength at point B?
The electric field is stronger where the separation between the equipotential lines are smaller and weaker where this separation is larger. At point A, the equipotential lines are largely spaced compared to point B. Therefore, the electric field strength at point A is smaller than the field strength at point B.
Where are equipotential lines more dense?
At point A, the electric field is the strongest. My professor said it was becuase the lines are densest. So the change in voltage per length is the greatest.
What can you say about the electric field strength in a region where the equipotential lines are close together as opposed to a region where they are far apart?
Every point on a given line is at the same potential. … When lines are close together, the slope is steep, e.g. a cliff, just as close equipotential lines indicate a strong electric field. Lakes are at the same elevation, in the same way conductors are at the same potential.
