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
