COM4LAB: AC Technology II

The COM4LAB course entitled “AC Technology II” is the second course on the fundamentals of AC technology. It addresses the behaviour of passive components in various circuits. Various combinations of coil, capacitor and resistance are analysed and calculated. The students are instructed on how to use the function generator, oscilloscope and multimeters. The course comprises 20 chapters.

Total duration: Up to 11 hours

Target audience

Among others, the course can be used to support the training process for the following professions:

• electrical system fitter
• electronics technician for automation technology
• electronics technician for energy and building technology
• electronics technician for devices and systems
• electronics technician for information and system technology
• electronics technician for machine and drive technology
• aircraft electronics technician
• information electronics technician
• system electronics technician

Learning objectives

The students should:

• be able to recognise the characteristics and connections in AC current circuits and
• be able to use the function generator and the oscilloscope.

Topics

The course covers the following topics:

• generation of AC voltage
• characteristic variables in AC technology
• Ohmic resistance in an AC circuit
• coil in an AC circuit

  inductive reactance – series connection of resistor and coil – parallel connection of resistor and coil

• capacitor in an AC circuit

  capacitive reactance – series connection of resistor and capacitor – parallel connection of resistor and capacitor

• series connection of resistor, coil and capacitor
• parallel connection of resistor, coil and capacitor
• series compensation
• parallel compensation
• series resonance
• parallel resonance

Previous knowledge

The students do not need any previous knowledge of electrical engineering in order to be able to complete the course successfully. Dealing with simple formulas is, however, required.
