What will happen to the electric field when a dielectric is placed?
The electric field is weakened when a dielectric is inserted.
What is the relation between energy and charge?
The relationship between energy and charge is potential difference or voltage. Where a volt is defined as existing between two points in an electric field when one joule of energy is required to move a charge of one coulomb between the two points.
What is the nature and characteristic of the electric fields?
the nature and characteristic of an electric field
How does a capacitor store energy?
The energy stored in a capacitor is almost entirely in the electric field produced between the plates. It takes energy from a battery or some other power source to move electrons to one of the plates and away from the other. This makes one plate positively charged and the other negatively charged. Electric field is produced in proportion to the charge per unit area on a plate, and this electric field is said to originate on positive charges and terminate on negative charges. Energy stored in electric fields is proportional to the square of the electric field strength and the volume of the field. The energy is transferred from the power source to the electric field through the rearrangement of electrical charges.
How do you calculate the electric field inside a conductor?
A spherical conductor with a radius of 14.0 cm and charge of 26.0 microcoulombs. Calculate the electric field at (a)r=10.0cm and (b)r=20.0cm and (c)r=14.0 from the center.
What is the voltage at the location of a Coulomb charge that has an electric potential?
The voltage at the location of a Coulomb charge with an electric potential is the work required to move a unit positive charge from a reference point to that location. It is a measure of the potential energy per unit charge at that point in the electric field.

What is the value of the electric field intensity in a region where the charge density is 5 newtons per coulomb?
The value of the electric field intensity in a region with a charge density of 5 newtons per coulomb is 5 newtons per coulomb.
How do you calculate electric potential difference when an electron move fro A toB along an electric field and0.000000000000000000394 J of work?
potential difference between two points equals the Work done to get to from A to B (in Joules) divided by the charge in Coulombs of the particle that is moving from A to B. If the particle was 1.60x10^-19 Coulomb, then the EPdifference, in Volts, is about 2.5. Volts is Joules/Coulomb. Think of it in terms of regular gravitational potential energy, where the potential energy is equivalent to the amount of force done to move an object of a certain weight (think coulomb) a certain distance (force over a distance is Work in Joules).
What is the unit for electric field?
The unit for electric field is newtons per coulomb (N/C) or volts per meter (V/m).
Unit for expressing strength of electric field?
Neuton per coulomb(N/C)
What is the dimension of electric potential?
The dimension of electric potential is energy per unit charge, which is equivalent to joules per coulomb or volts. It is a scalar quantity that represents the amount of work needed to move a unit positive charge from a reference point to a specific point in an electric field.
What are the characteristics and effects of a non-Coulomb electric field?
A non-Coulomb electric field has characteristics that deviate from the traditional Coulomb's law, which describes the force between charged particles. In a non-Coulomb electric field, the force between charges may not follow a simple inverse square relationship. This can lead to more complex interactions between charged particles, resulting in different effects on the behavior of the charges in the field. These effects can include non-linear force relationships, the presence of magnetic fields, and the generation of electromagnetic waves.
How to find the electric field at a point in a given system?
To find the electric field at a point in a given system, you can use Coulomb's law or Gauss's law. Coulomb's law involves calculating the electric field due to individual charges in the system, while Gauss's law allows you to find the electric field by considering the total charge enclosed by a Gaussian surface around the point of interest. By applying these principles, you can determine the electric field strength and direction at a specific point in the system.
What method can be used to find the magnitude of the electric field in the wire?
To find the magnitude of the electric field in a wire, you can use Coulomb's law, which states that the electric field strength is directly proportional to the charge and inversely proportional to the distance from the wire.
What is in potential?
A little complicated, but here are two examples: In electric fields, a potential of 5 Volts means that if a 1 coulomb charge were placed there, it would have a potential energy of 5 Joules. In gravitational field, a potential of 5 J/kg means that if a 1 kilogram mass were placed there, it would have a potential energy of 5 Joules.
