Key Topics to Revise

1

Electric Current and Circuit

  • Electric current is the flow of electric charges through a conductor
  • Conventional current flows from positive to negative terminal (opposite to electron flow)
  • Current is measured in amperes (A) using an ammeter connected in series
2

Electric Potential and Potential Difference

  • Potential difference is the driving force for current flow
  • Work is done to move charges from one point to another
  • Battery provides potential difference through chemical energy
3

Ohm's Law and Resistance

  • Ohm's law states V ∝ I at constant temperature
  • Resistance opposes current flow in conductors
  • V-I graph for ohmic materials is a straight line through origin
4

Resistors in Series and Parallel

  • Series: Resistors connected end-to-end, current same throughout
  • Parallel: Resistors connected across same two points, voltage same across each
  • Series total resistance = sum of individual resistances
