Introduction

Electronics is the branch of physics, engineering and technology dealing with electrical circuits that involve active electrical components such as vacuumtubes, transistors, diodes and integrated circuits, and associated passive interconnection technologies.
In this formal support I going to explain how my project its function , the materials and the procedure tobuild it .

The objective of this circuits its do the wheastone circuit, the reason for do that kind of circuit its to move the motor to the right and the left depend of how many current and voltageits passing inside the corners wires.

Description and definition of the problem

-what are the function of this circuit ?

Recompilation data

Materials
Wires
2 variable resistances
2resistances
A circuit plaque
An electric motor
A battery
Procedure
-I put the variable resistance together and do the same thing with the resistance also take two wires and connect every one of theresistance variable center to a resistance to complete the diamond.
- After have the diamond connect one battery wired to the third point in one variable resistance and the another wired connect to the10 ohms resistances.

- When I have everything together I connect two wires everyone from the motor to each one of the resistance variable center.

Results and functionally
When I finish thework, I prove it and I have good results at the second time , because the first time one of the resistance variable its damage.
Now how that circuit work?
When you close the switch, the current goingto pass for the variable resistance and the 10 ohms resistance in each one of the two sides, when you connect to the motor and increase the resistance in one side, the motor going to turn around in...
