You turn an electric dipole end for end in a uniform electric field.How does the work you do depend on the initial orientation of the dipole with respect to the field?
The work done by you to turn the electric dipole end for end in a uniform electric field depends on the initial orientation of the dipole with respect to the field. If the dipole is initially oriented such that its positive and negative charges are parallel to the electric field, then no net work is done as the electric field does not do any work on the dipole as the electric field lines do not transfer any energy. On the other hand, if the dipole is initially oriented such that its positive and negative charges are perpendicular to the electric field, then work is done by you to turn the dipole as the electric field exerts a force on the charges in the dipole in opposite directions, causing them to move in opposite directions. As a result, you have to do work to move the charges and turn the dipole.
Conservative Nature of induced electric field?
The conservative nature of induced electric field is due to time varying magnetic fields. This occurs because the work done in moving a charge in a closed path in this field is not zero.
What is relation between electric field and energy?
Electrical energy is produced through the motion of a conductor within an electromagnetic field produced by a magnet. In this way, electromagnetic fields are absolutely critical to the production of electric energy.
Can electric field lines do work?
Yes. Work is force times distance, or technically the dot product of vector force times vector distance. Electric fields exert force on charge and the force does work when the charge moves in the direction of the electric force. (In the converse, when the movement of charge is against the direction of force, work is transformed into stored electromagnetic energy.) Technically, it is the electric field that does work and not the field line. Mother nature produces electric fields, but humans can not see electric fields. Humans invented the idea of field lines to create a mental picture of the field. The two most common ways are to draw lines in space or to draw a collection of arrows in space. Note: One should not confuse this answer with the question of whether work can be done by a magnetic field. A magnetic field can not do work because the direction of the magnetic force is always perpendicular to the direction of motion of charge and hence the dot product of force and distance moved is always zero.
Work done in a conservative field?
Because in conservative field the total energy is conserved therefore the work is zero

When a charge is moved from one point to another in an electric field the work done is?
then our work is positive
What is the name given to work done per Coulomb?
It is the work done to moving a unit positive charge or test charge from one to another point in electric field this work done is called the potential difference.
When a charge is moved from one point to another in an electric field then what is the work done?
zero along the direction of the field
When charged is moved from one point to another in an electric field the work done is?
zero along the direction of d field
What is is true about electric field around an electric charge?
Everything. A positive charged particle generates an electric field equivalent to the work done in bringing a unit positive charge from infinity to near that charge.
A charged particle of charge q is rotating in an electric field E What is the work done by the field when the charge comletes a rotation?
zero

What do you mean bu electric potential?
It is the work done due to accumulation of electric charge.
Is current is the rate which work is done?
no. in simple words work done between two points in a circuit is potential difference across two points. The voltage between two ends of a path is the total energy required to move a small electric charge along that path, divided by the magnitude of the charge. Mathematically this is expressed as the line integral of the electric field and the time rate of change of magnetic field along that path. In the general case, both a static (unchanging) electric field and a dynamic (time-varying) electromagnetic field must be included in determining the voltage between two points.
