In this double lesson, the repair of a broken cable is demonstrated using the example of a defective charger. Step-by-step instructions are used for this. The repair task described in the instructions can be applied to many different objects. It is crucial for the lesson that the cables to be repaired are only used in the lower extra-low voltage range.

Students should bring their own chargers or headphones. Otherwise, this is to be done by the teacher. An appropriate number of instructions should be provided.

Recommendation: The "soldering exercise" module is a good preparation for this repair task.

* Soldering iron
* Soldering tin
* Cutter knife
* Side cutter
* Heat shrink tubing
