  • 1. 1 Everything Science www.everythingscience.co.za 16. Electrostatics Physics: Electricity and magnetism Grade 10
  • 2. 2 Everything Science www.everythingscience.co.za Two types of charge All objects surrounding us (including people!) contain large amounts of electric charge. There are two types of electric charge: positive charge and negative charge. Positive charge is carried by protons in the nucleus. Negative charge is carried by electrons. Objects can be positively charged, negatively charged or neutral. Objects that are neutral have equal numbers of positive and negative charge. Objects can change their charge by contact or by rubbing: neutral objects can become either positively charged or negatively charged.
  • 3. 3 Everything Science www.everythingscience.co.za Forces between charges and charge conservation Unlike charges are attracted to each other and like charges are repelled from each other. The principle of conservation of charge states that the net charge of an isolated system remains constant during any physical process, e.g. two charged objects making contacting and separating. When two identical conducting spheres on insulating stands are allowed to touch they share the charge evenly between them. We can calculate the resulting charge using: Q= Q1+Q2 2
  • 4. 4 Everything Science www.everythingscience.co.za Q=nqe Conductors and insulators Conductors allow charge to move through them easily. Insulators do not allow charge to move through them easily. Quantisation of charge Charge is measured in coulombs (C). Charge is quantised in units of the charge of an electron: 1,6 × 10−19 C. We can use the following equation to calculate charge:
