The field around a charge
Every charged object has an electric field around it: the region where another charged object feels a force.
Field lines show the field. The arrows give the direction of the force on a small positive charge.
Around an isolated charged sphere the lines are straight and radial: outwards from a positive sphere, inwards to a negative one.
