   • Perform hands-on experiments with resistors, capacitors, and inductors to observe their real-world behavior in circuits.
   • Test theoretical concepts such as voltage division, filtering, and reactance using simulators and breadboards.

What are the knowledge prerequisites?

This course is designed for complete beginners, so no prior knowledge of electronics or electrical engineering is required. It starts from the very basics and gradually builds up to more complex topics. However, a few basic skills and knowledge areas can help you get the most out of the course:

1. Basic Math Skills:

   • A familiarity with basic arithmetic (addition, subtraction, multiplication, and division) is essential for working through calculations involving voltage, current, resistance, and power.
   • Knowledge of simple algebra is useful, particularly when applying Ohm’s Law, Kirchhoff’s Laws, and solving equations for circuit analysis.

2. Familiarity with Basic Tools and Technology:

   • While not required, it can be helpful if you’ve previously used basic tools like a multimeter or worked with a breadboard, but the course will guide you through these tools step by step.
   • If you’ve worked with computers or software before, that’s a plus, as you’ll be introduced to circuit simulation software.

3. Interest in Hands-On Learning:

   • This course involves practical experiments and working with real circuits, so students who enjoy hands-on projects and learning by doing will benefit greatly.

If you are comfortable with basic math and eager to learn about electronics through practical experimentation, you are ready to start this course!
