Understanding Basic Electrical Concepts and Circuits
The Atom
The atom is the basic unit of matter. It consists of a nucleus containing protons and neutrons, around which electrons revolve. Electrons carry a negative charge, while protons carry a positive charge. Neutrons and other particles have their own charges.
Electric Charge
Electric charge is a fundamental property of matter responsible for electrical phenomena. The continuous displacement of electrons is called electric current.

Vi: Instantaneous Tension
Vi represents the tension at a specific instant in time over a given angle.
Vp: Maximum Coil Tension
Vp is the maximum tension generated by the coil.
Counter-Electromotive Force
When the engine is spinning, it acts as a power generator, producing a counter-electromotive force that opposes the applied voltage.
Vblokeo: Starter Block Voltage
Vblokeo is the voltage measured at the battery terminals when the starter is blocked.
F: Frequency
F is the number of cycles performed in one

Key Mechanical Principles
Force (F) is any action that modifies the state of rest or motion of a body. It is measured in Newtons (N). A moment of a force (M) is the product of the value of the force by the distance between that point and the point of application of the force. Its unit of measurement in the SI is the Newton-meter (Nm). Work (W) done by a force is the product of the force produced by the displacement. In the SI, work is measured in Joules (J). Power (P) is the work done per unit of

External Storage Systems
Definition
External storage systems, also known as peripheral units or devices, facilitate communication between the CPU and the external world. They serve as mass storage systems or auxiliary means capable of storing information permanently and retrieving it automatically.
Structure
External storage systems consist of two main parts:
- Mechanical Part: Composed of electromechanical devices controlled by mechanical elements.
- Electronic Part: Interprets orders from the CPU, handles

Instruments
Instruments are composite objects for one or more pieces combined with each other that help when performing a path.
- Ruler: An instrument comprising a scale with graduated numbering (cm or mm). Its use is to draw lines and measure.
- T-Square: An instrument made of two parts (leaf and head). Its function is a horizontal support for other instruments and serves to draw parallel lines.
- Squares: These are triangular instruments used
Electric Circuits and Semiconductor Fundamentals
Fundamentals of Electric Circuits
Fundamentals:
a) Voltage, tension, or DDP – Indicates the energy difference between points in a circuit. They are measured in volts (V).
b) Intensity or Current (I) – Number of electrons flowing through the wire. It is measured in amperes (A).
c) Resistor (R) – The opposition a material offers to current flow. It is measured in ohms (Ω).
