  1. Anglicky v odborných předmětech"Support of teaching technical subjects in English“ Tutorial: Mechanic - electrician Topic: Technicaltraining II. class Passivecomponents – coils Prepared by: Melichařík Lubomír Projekt Anglicky v odborných předmětech, CZ.1.07/1.3.09/04.0002 je spolufinancován Evropským sociálním fondem a státním rozpočtem České republiky.

  2. PASSIVE COMPONENTS– COILS Coil • Is an electrical component used in electrical circuits: • -to create a magnetic field electrical current • -serves as an electromagnet • -induce a variable magnetic field in an electric current • -as an inductor (inductance bearer).

  3. COIL Electrotechnical schematic symbol: Schematic symbol of coils, inductance, chokes Schematic symbol of coils, variable inductance, tuning coils Schematic symbol of coils with a tap Schematic symbol of coils with a magnetic core Schematic symbol of coils with a ferrite core

  4. PRINCIPLE AND CHARACTERISTIC OF COILS • Construction of coils • -consists of wire wound on an insulating supporting frame • -winding can be single-layer or multi-layer • -the wire-wound may be self-supporting – no skeletons. • -wire in the coil has to have the lowest resistivity, that the coil avoids large heat losses • -most commonly used material is copper • -to increase the magnetic properties insert a core inside the coil

  5. PARAMETERS OF COILS • Parameters of coils • -the basic unit to which the multiplier is applied is the inductance microhenryμH. • -the number of turns • -geometric properties (number of turns per unit length, length, section content) • -inductance – expresses the magnitude of the magnetic flux in a unit of electric current • -maximum load- the highest possible power output of a current friendly electrical coil • -maximum current – the largest current that can pass through the coil.

  6. TYPES OF COILS • Types of condensers air toroids, ferrite antenna, vf coils a others coils

  7. COIL SORTING AND CALCULATIONS

  8. Activities for students– mandatory slideTask, test, questions … . • Calculate the resulting inductance of the series connection of these coils. • Name the types of coils

  9. Activities for students– mandatory slideTask, test, questions … . Two slides are best. • Calculate the resulting inductance of the parallel connection of these coils. • Name the coils used in practice.

  10. Bibliography • Václav Malina Poznáváme elektroniku I. • Adrian Schommers Elektronika tajemství zbavená. ISBN 3-92608-32-5
