A classic: the simple electrical circuit and / or parallels as an experiment for children in primary school. Given their ease, teachers used this experiment to teach their students how an electrical circuit works, whether parallel or simple. Let's review how a homemade electrical circuit is made.
What we will need:
1) Rectangular wooden board.
2) 2 light bulbs.
3) 2 lampholders.
4) A long enough copper cable.
5) 1 pile.
6) Strip, or preferably insulating tape.
7) 2 switches.
Process:
1) First, we stick the battery to the board with the tape.
2) We cut a piece of wire and peel both ends. Then we attach one end of this to the pile.
3) Then, we connect this cable to the socket, which in turn will be attached to the bulb.
4) On the other side of the socket we connect another piece of cable, which we wrap with electrical tape.
5) At the other end of this same cable, which should also have both ends stripped, we connect a switch.
6) We will also reinforce this cable with the insulating tape. We connect this cable with another piece of cable, also wrapped in electrical tape
7) And at the opposite end of this cable, we connect to another lampholder (with its respective bulb).
8) And finally, we put another piece of cable reinforced with tape to the pile.
Useful data
We must bear in mind that an electric circuit is so called because all its parts form a circuit, that is, electricity travels in a circle through all its components. So we have to make sure that all the cables are well connected with the switches, light bulbs and the battery, because if it is not properly connected at any point in the circuit, the electricity will be cut off. It is also a useful experiment to learn how to make electrical circuits for children.
