How do you find the electric field of a wire?

How do you find the electric field of a wire?

If we assume the electric field is constant inside the wire, it is known that the voltage drop is equal to the electric field times the length of the segment of wire. So I*R=E*L. Resistance is defined as resistivity times the length of wire over the cross-sectional area.

Is there electric field inside a current carrying wire?

Answer: Electric field inside a current carrying conductor is zero as the charges inside it distributes themselves on the surface of the conductor. The net charge in the current carrying wire is zero.

What is in an electric field?

Electric field is defined as the electric force per unit charge. The direction of the field is taken to be the direction of the force it would exert on a positive test charge. The electric field is radially outward from a positive charge and radially in toward a negative point charge.

Is the electric field the same everywhere?

At a point in space, the direction of the electric field is tangent to the electric field line that passes through that point. The magnitude of the electric field is strongest in regions where the field lines are closest together. In both drawings I and II the electric field is the same everywhere.

What is dipole of an electric field and electric dipole moment?

Electric dipole moment definition :- The dipole moment of an electric field is a vector whose magnitude is charge times the separation between two opposite charges. Direction of dipole moment is along the dipole axis from negative charge to positive charge.

What is the electric field at the midpoint of a dipole?

In the middle of the dipole, the electric fields contributed by both charges are in the same direction; they are both pointing toward the negative charge. Thus, the magnitude of the electric field is the sum of the contribution of the two charges.

What will be the value of electric field at Centre of dipole?

10-29C.
