Study Notes
Electric Energy: Provision and Transfer
Generators
- See video "Functioning of a Generator"
Structure and Function
- Inside the generator, a magnet and an induction coil are moved relative to each other.
- This causes the magnetic field in the coil to change constantly.
- This induces an alternating voltage in the induction coil.
- A generator can be an electromagnet as rotor
Types of Generators
- In internal pole generators, the magnetic poles rotate inside the induction coils.
- In external pole generators, the magnetic poles are located outside the rotating induction coils.
Energy conversion
- Rotational energy is converted into electrical energy by the generator, releasing thermal energy.
