# Physics 1, Part 2: Electrical Engineering (EEng), WS2022/23

Course: **E_1.08 Physics: Mechanics, Electricity and Magentism, WS2022/23**, Part 2: “Electrical Engineering”

Course ID: **EE_1.08_2** (part of EE_1.08)

## Structure of E_1.08 Physics: Mechanics, Electricity and Magentism

We group the topics “electricity” and “magnetism” together under the term **electrical engineering**.

The course EE_1.08 consists of two course parts:

- Mechanics (EE_1.08_1) and
- Electrical Engineering (EE_1.08_2).

The two course parts are conducted separately by two lecturers.

Course Part | General Topic | Abbreviation | Course ID | Lecturer |
---|---|---|---|---|

Part 1 | Mechanics | Mech | EE_1.08_1 | Dr. Irmgard Buder |

Part 2 | Electrical Engineering | EEng | EE_1.08_2 | Dr. Rolf Becker |

## Exam and Grading

**UPDATE ON GRADING:
Written Exam: 100 points,
Lab Exercises: 20 EXTRA points!**

The two course parts form **one module with one exam**.

You will **pass** the module with **50 points**.

**100 points** is scored as **1.0**

**120 points** is scored as **1.0**

The scores are distributed as follows:

Part | | New Points Allocation | |
---|---|---|---|

Mech | written exam | | 50 |

EEng | written exam | | 50 |

EEng | lab exercises | | (extra lab points) 20 |

max | | 100 (+20) |

#### Examples

Points | Score |
---|---|

< 50 | FAIL |

50 | pass |

30 (written) + 20 (lab) = 50 | pass |

45 (written) + 5 (lab) = 50 | pass |

100 (written) + 0 (lab) = 100 | 1.0 |

80 (written) + 20 (lab) = 100 | 1.0 |

100 + 20 (lab) → 100 (limited) | 1.0 |

# EEng Lecture

- Lecture Room: 01 00 215 (HS 1)
- Lecture Time: THU, 12:15 - 15:30

#### Lecture

The lectures will be given live on campus. At least the EEng part will be streamed, recorded and uploaded for later offline access.

The links to the videos are shared on the Discord channel of this course.

#### Relationship with other Courses

The course EEng is used to lay the foundations for the following courses:

- (EE_2.03) Physics 2: Thermodynamics, Radiation, Heat Transfer,
- (EE_3.02) Energy Technology,
- (EE_4.03) Applied Measurement and Control

## Lab Teams, Lab Groups and Lab Exercises

**UPDATE:** Each student can earn **20 EXTRA points** max by completing **$\ge$ 4 lab experiments**.
