ELECTRIC FIELD
Learning Outcomes
20.1 Describe an electric field as a region in which an electric charge experiences a force
20.2 Define electric field strength as force per unit positive charge acting on a stationary point charge
20.3 Calculate forces on charges in uniform electric fields of known strength
20.4 Use � strength of a point charge in free space or air
20.5 Illustrate graphically the changes in electric field strength with respect distance from a point charge
20.6 Represent an electric field by means of field lines
20.7 Describe the effect of a uniform electric field on the motion of charged particles
20.8 Understand the concept of electric flux of a surface
20.9 State Gauss law and apply it for a field of a charged sphere and for line charge
20.10 Understand that uniform field exists between charged parallel plates and sketch the field lines
