Formulas:

An electric field is a measurable effect generated by any charged object.

A field carries energy and passes it on to other charged materials by exerting electric forces.

Michael Faraday said every charged object generates an electric field that creates space and exerts a force on all charged particles it encounters.

Electric forces are used to bring power to your home, charge your computer, and light up the screen that you're using to watch this video.

Ellectric Fields

An electric dipole is when we have a negative and positive charge with a equal and opposite magnitude of charge.

When it is a negative charge arrows point in, when it is a positive charge arrows point outside

The purpose of the electric field lines is to show the magnitude and direction of the force exerted on any nearby positive test charge. if the lines are thicker it means there is more charge in it

Properties:1. The field lines must be tangent to the direction of the field at any point. 2. The greater the line density, the greater the magnitude of the field. 3. The lines always start from positively charged objects and end on negatively charged objects (+ to -) 4. The lines must never cross.
