Static electricity

• What is static electricity?

  charged particles do not move but they still exert a force on each other
• What do conductors do?

  Allow charge to flow through them
• What do insulators do?

  charge can't flow through them so a build up of charge can occur on the surface and remains static
• What is an electric field?

  the region that a positive or negative particle will feel a force around it
• Where is an electric field strongest?

  where lines are closer together, nearest the object
• Where is an electric field the weakest?

  where the lenses are further apart, further from the charge
• What is electric current?

  Flow of electric charge.
• What is a series circuit?

  there is only one path for the current, so the current is the same through the circuit
• What is a parallel circuit?

  has junctions with more than one route for current
• What is resistance?

  anything that reduces the flow of charge. measured in ohms
