How do you tell where the electric field is 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.
Why is the electric field in a capacitor constant?
1) The field is approximately constant because the distance between the plates in assumed small compared to the area of the plates. The field is zero approximately outside of the plates due to the interaction of the fields generated by the two plates (They point in opposite directions outside the capacitor).
Can field lines cross each other?
Electric field lines cannot cross. … This is because they are, by definition, a line of constant potential. The equipotential at a given point in space can only have a single value. If lines for two different values of the potential were to cross, then they would no longer represent equipotential lines.
Why do the electric field lines never cross each other?
Answer: Electric field does not direct in two directions that is why electric field lines never cross over each other. … When two lines intersect each other, tangents are drawn at that point indicating two directions of electric field lines, which is impossible therefore electric field lines cannot cross over each other.
What is the formula for a capacitor?
The governing equation for capacitor design is: C = εA/d, In this equation, C is capacitance; ε is permittivity, a term for how well dielectric material stores an electric field; A is the parallel plate area; and d is the distance between the two conductive plates.
Is the electric field the same everywhere in a capacitor?
The electric field between two capacitor plates is approximately constant.
Why is force constant in a uniform electric field?
Electric force around a point charge is very similar to gravitational force around a point mass. A uniform electric field consists of two conducting plates. These plates are oppositely charged, and infinitely wide. … This force remains constant as the charge travels within the electric field.
