Magnetism and electricity: Identify, describe, and apply principles of electrostatics (static electricity)
Subject outcome
Subject outcome 4.2: Identify, describe, and apply principles of electrostatics (static electricity).
Learning outcomes
- Identity two kinds of charge and describe how an object becomes charged.
- Define the law of conservation of charge.
- Identify and predict the distribution of charge over the surface of a conductor (spherical and non-spherical).
- Identify and predict action between electric charges, the attraction between charged and uncharged objects and action of highly charged points.
- Identify and describe electrostatic induction.
- Apply the principle of discharge to a charged rod using ions in a flame and ions in the atmosphere and atmospheric electricity and the use of a lightning conductor.
