Subject content
Make sure you have up-to-date course notes. Use them, and if you haven't got them see your teacher. The topics you may be tested on are:
- Phenomena, concepts, and principles:
- static electricity:
- positive and negative charge
- conductors and insulators
- uniform and non-uniform charge distributions
- earthing
- electrical discharge in air
- separation of charge by friction, charging by contact and induction
- DC electricity:
- voltage
- current
- resistance
- power
- circuits (no resistive component in series with the source):
- series
- simple parallel
- circuit diagrams
- magnetism:
- magnetic field directions
- interactions and the result of interactions including:
- magnetic field of bar magnets
- Earth’s magnetic field
- magnetic fields due to currents in straight wires
- magnetic fields due to currents in solenoids
- right-hand grip rule
- electromagnet Check out the revision on electricity
