Aims
On completion of this TLP you should:
- Understand the meaning of the terms dielectric constant, dielectric loss and dielectric breakdown.
- Recognise that the properties of dielectrics are due to polarisation and understand how this polarisation arises on the microscopic scale.
- Understand how material structure, temperature and frequency affect the properties of dielectrics.
- Be aware of some practical applications of dielectric materials.
