Lesson 3. Electricity. This is a very simple introduction to electricity and electronics. There are some difficulties when studying electricity:
  • 1ª.- We can't see electricity, but we can see effects it makes (light, movement, heat, etc.)
  • 2ª.- Probably you won't have studied yet anything about electricity because it is not included in primary education.
Now we will know how electricity works, in this lesson, and you can practise with this phenomenon natural. Come on!!!!!
