Basic Electrical Circuits (BEC)

DU Title: Basic Electrical Circuits (BEC)

Subject: Charging and Starting Systems (CSS)

Course/Level:  1st / Vehicle Electromechanics

The aim of this didactic unit is that students raise the ability to design, calculate, assemble and interpret basic electrical circuits with different components, analyze the variation of the fundamental parameters and bring students closer to the practical interpretation of circuit theory based on the reality that they know or are familiar to them.

Learning outcomes / Evaluation criteria:

To apply electricity and electromagnetism laws and rules to basic electrical circuits.

To Calculate fundamental parameters of basic electrical circuits.

To assemble / disassemble basic electrical and electronic circuits.

Subject Content:

Basic parameters of electricity.

Electrical parameters measurement units.

Ohm´s law (formula).

Electric power formula.

Series circuits / Parallel circuits.

Basic components of electrical circuits: Sources, batteries, cables, resistances, capacitors, light bulbs, motors, fuses, switches, multimeter, voltmeter, ammeter.

6. Activities:

1) Reading Comprehension: Read the following explanation of AC / DC. Afterwards, match sentences A-F with sentences 1-6.

2) Vocabulary activity: Would you be able to solve this wordsearch?

3) Listening activity Watch this Video related to AC/DC. Listen twice, then fill the gaps.

4) Speaking and Writing activity: In groups of 4 students: Discuss about the advantages, disadvantages and applications of direct current and alternating current, watched on the previous video.

5) Reading comprehension: Read the text about Ohm´s law & power measurements.

6) Reading comprehension: Enter your "Pinterest" account and search for the link bellow. Open the document clicking on evatnoh23.wordpress.com. Have a look to the document and match the expressions

7) Useful resources Use these formulas to calculate

8) Useful resource Use this App to calculate

9) Calculation exercises: In the following circuits, calculate the current flowing through each of the resistors, as well as the power they consume. Apply Ohm´s law and electric power formulas Pie Chart.

10) Simulation exercises: From the circuits of the previous exercise, use "Falstad" App to design them and simulate their operation.

11) Listening activity: Watch this Video related to "Ohm´s law experiments"

11) Speaking and Writing activity: In groups of 4 students: Discuss about things you´ve learnt from the previous video and write a summary of the experiments performed on the video.

12) Comprehension activity: Practice how to identify a resistor value according to its color code

Final Task:

13) Collaborative work in electrical workshop: In groups of 4 students, assemble a vehicle headlights power circuit with switching off / parking light / dipped beam light / main beam light.

14) Collaborative work in electrical workshop: Taking in account the previous activity work, create a SLIDETALK presentation explaining your work step by step.

Methodology.

Eminently practical application of electrical  fundamental laws to calculate, design and assemble vehicle electrical circuits.
Carrying out activities and tasks in electrical workshop collaboratively in groups or couples, where the suitability of the solutions adopted is discussed.
Promotion of manual skills for electrical circuits assembly and disassembly.
