What are the 4 main rules for diagramming electric field lines?
1 Answer
- 1) Electric field lines are always drawn from High potential to.
- 2) Two electric field lines can never intersect each other.
- 3) The net electric field inside a Conductor is Zero.
- 4) Electric field line from a positive charge is drawn radially outwards and from a negative charge radially inwards.
Can an electric field be positive?
Because positive charges repel each other, the electric field around an isolated positive charge is oriented radially outward. When they are represented by lines of force, or field lines, electric fields are depicted as starting on positive charges and terminating on negative charges.
How is an electric field generated?
A charged object creates an electric field – an alteration of the space or field in the region that surrounds it. Other charges in that field would feel the unusual alteration of the space. Whether a charged object enters that space or not, the electric field exists.
At what two types of locations can electric field lines start?
Electric field lines
- Lines begin and end only at charges (beginning at + charges, ending at – charges) or at Infinity.
- Lines are closer together where the field is stronger.
- Larger charges have more field lines beginning or ending on them.
- Electric Field lines never cross (since E must point in a definite direction unless it is zero).
What is the work done formula?
| What is Work, Energy and Power? | |
|---|---|
| Work | |
| Definition | Work is said to be done when a force applied to an object moves that object. |
| Formula | We can calculate work by multiplying the force by the movement of the object. W = F × d |
| Unit | The SI unit of work is the joule (J) |
