Key Topics to Revise

1

Electromagnetic Induction - Basic Principles

  • Electromagnetic induction occurs when magnetic flux linked with a conductor changes
  • Relative motion between conductor and magnet is necessary for induction
  • Induced EMF depends on rate of change of magnetic flux
2

AC vs DC Current

  • Direct Current (DC) flows in only one direction - from batteries, cells
  • Alternating Current (AC) continuously changes direction at regular intervals
  • Electromagnetic induction naturally produces AC current
3

Electric Generator

  • Converts mechanical energy to electrical energy using electromagnetic induction
  • Two types: AC generator and DC generator
  • Main parts: Field magnet, Armature coil, Slip rings (AC)/Split rings (DC), Brushes
4

Power Stations and Energy Conversion

  • Thermal Power Station: Uses coal/gas → Heat → Steam → Mechanical → Electrical
  • Hydroelectric Power Station: Water potential energy → Kinetic → Mechanical → Electrical
  • Nuclear Power Station: Nuclear energy → Heat → Steam → Mechanical → Electrical
