Electric Current

My didactic unit title: Electric Current

This is the first unit of Intermediate Vocational Training Cycle "Electromechanical Maintenance" in the subject of Electricity and Electrical Automatisms.

I have considered the following learning outcomes:

- Understand the process of generation and transport of electric power. 

- Identify the electrical circuit and the parts that compose it. 

- Handle the most important electrical quantities. 

- Apply Ohm's law. 

- Know what the Joule effect and its consequences are. 

- Apply the concepts of power and energy. 

- Make measurements in direct current.

The objectives in this unit are:

-Generation of electric power. 

-Transportation of electric power. 

- Electrical circuit. 

- Electrical magnitudes. 

- Joule effect. 

- Continuous electric circuit. 

- Ohm's law. 

- Power in DC circuits. 

- Electric power. 

- Electrical measuring devices.
