Opis

The experiments are carried out using the STE plug-in system Electricity/Electronics.

Objectives

  • Recognition of basic physical principles
  • Implementation of electrical circuits according to circuit diagrams

Practically all electrical machines generate torque and forces from the interaction between magnetic fields and electric current. The transformation of electricity by transformers also requires magnetic fields which change over time. Student experiments on electromagnetism and induction therefore form the essential physical basis for understanding electrical machines.

The equipment set incorporates student experiments which can be carried out in a laboratory safely using safety extra-low voltage. Experiment instructions are contained in a manual in either printed or digital form.

The target group is made up of students in general or vocational education. The experiments are designed as an introduction at a simple level of understanding.

For more advanced work, the following sets are recommended:

  • E2.1.1.2 Three-phase transformers
  • E2.1.1.4 Generators and motors

Topics

  • Circuits, conductors and insulators
  • Change-over/two-way circuits
  • AND and OR circuits
  • Measurement of current and voltage
  • Ohm's law
  • How the resistance of a wire depends on material, length and cross section
  • Distribution of voltage along a current-carrying wire (potentiometer)
  • Resistors connected in series and parallel
  • Batteries connected in series and parallel
  • Terminal voltage and internal resistance of a voltage source
  • How resistance of a wire depends on temperature
  • Fuses, bimetallic switches, thermostats
  • Power and work associated with electric current
  • Magnetic effect of electric current
  • Current carrying conductors in an magnetic field
  • Magnetic field of a coil
  • Soft iron instruments/magnetic relays/buzzers/speakers
  • Electromagnetic induction
  • Transformers
  • Current and voltage transformation
  • Self-induction by a coil
  • AC generators, synchronous motors
  • Coils and capacitors
  • DC resistance and AC impedance of a coil
  • Capacitors in DC and AC circuits
