Electric fields

• An electric field is a region in which a charged object will experience a non-contact electrical force
• Electric fields can be found surrounding any charged object
• • The electric field is strongest close to the charged object
  • the further away from the charged object, the weaker the field
• • A second charged object placed in the field experiences a force
  • The force gets stronger as the distance between the object decreases.
• In situations where sparks are unwanted, what precaution must be taken to prevent the build up of static charge?

  Any surfaces that are rubbing against each other should be earthed to allow the charge to flow off the materials.
