Reaching information

At the beginning I reach in the book how to make acircuit. In the book show a small circuit with a battery of 9V and bull lights as resistances of 4.0 ohms 2.0 ohms and greaters. But I search other options. On other option was to make a circuit in aelectronic plate. With led bulls as resistance. And a small battery. This was even complicated. So I look other option with my brother. That was use a car battery and small light bulls as resistances.With a more thick wire. This was the best option. So I buy 3 light bulls. Enough copper wire and two pars of alligators.

Procedure

I cut the wire. With the length I think it was necessary.Then I take out the covering rubber of the wire but only in the tips.
The wire was to thick so I cut two copper strings in order to the wire pass through the rosette connectors.
With a clip Ithread the wire in the connectors. Each rosette have two connectors. So I thread each extreme of the wire in each connector.
I cover the area with insulating tape for security.
I repeat the processof cutting the rubber of the tips.
With the clip I separated three copper strings and pass it through the alligator little pin inside. (both sides of the wire)
I cover the area with insulatingtape.
I test the circuit with the battery and electricity.

I make two circuits one in parallel and one in series. The one in series is the simplest it has only one resistance. The parallel one havetwo resistances. For the parallel one the only thing that changes are the joints. I do all over again the procedure complete. Then I do the procedure again until the part when I use the alligators.Instead of that I carefully cut in the middle of the complete second series circuit the covering rubber. Taking care of not cutting the copper strings. Then I do the joints with the tips of the not...
