In the area of direct and alternating current technology, this package is designed to familiarize the students step by step with the principal concepts of electrical circuits and component behavior through practical investigations. The package contains a special set of cards designed to work with the main unit to introduce the students to the basics of AC & DC electrical circuit theories through interactive experiments.
- The experimental cards contain a collection of active, passive elements and a lot of electrical components such as resistors, switches, lamps, LEDs, resistors, capacitors, inductors and etc. with different types and ratings.
- They also comprise voltage divider circuits, light and voltage-dependent resistors, Fire Alarm Model, and LC - LR - RLC circuits. In addition, a lot of circuits can be configured using the components of the cards.
- The experimental cards include : Introduction to electricity , DC Electric Circuits I (EC - 001.5.2), DC Circuits II (EC - 001.5.3), AC Circuits I (EC - 001.5.4) , AC Circuits II (EC - 001.5.5)
