These pages deal with electric circuits, electrical energy, electrical energy production and electrical energy transmission.

More specifically:
We press a switch and we turn the lights on. How is this possible to be happening?
Let's construct a simple circuit.
Let's improve a bit the simple circuit we just created. 
Can we connect more light bulbs? If yes, in how many different ways can we do that?
What do we mean by the term "induction"? 
How does an electromagnet work?
What is electrical energy? How do we produce electrical energy?
How is electrical energy coming to our houses?
What is the function of a transformer?

Warning: all experiments should be performed using batteries and small light bulbs used in electric torches. Do not ever try performing any of these experiments using power from electric socket and/or using household lamps. (There is danger of electric shock - Electrocution).

In most of the pages, there is a list containing the materials needed for the experiment, a video explaining how to use these materials, and the explanation of what we observe during the experiment and why.

In certain points some extra info is offered (just follow the links)
In others there are questions prompting the user for some action.
We suggest you to collect the materials and perform the experiments by yourselves.

You can find a light bulb in an electric torch (take them out carefully and place them back when you finish). Sometimes the spirals of ordinary notebooks contain wire. In such cases you can use that instead of other cable. If the cable has no plastic coating, do not touch it with your fingers (or hands), while being connected to the battery as the cable may get too hot.
