- Sections and slides rewritten in Swedish; German law and institutions replaced by Swedish/CEPT/ITU equivalents (PTS, SSA, PTSFS 2025:1, SSMFS 2008:18), unverified statements marked "% TODO VERIFY" - New toc: INSTEG, HAREC, UPPGRADERING; section idents are Swedish (see ident-map.tsv) - Exam-question tags, BNetzA question pool, solutions and the German SWL course removed - Static pages, snippets, applets, READMEs and image alt-texts translated - TikZ labels translated; SVG drawings regenerated (drawing 689 still fails to build upstream: it references a missing photo) - Changed from the original: not endorsed by DARC e.V., SSA or PTS Co-Authored-By: Claude Sonnet 5.5 <[email protected]>

* Elektriska apparater har en angiven effektförbrukning
|
|
* Exempel: LED-lampa $\qty{7}{\watt}$, dammsugare $\qty{425}{\watt}$
|
|
* I varje motstånd omsätts elektrisk effekt
|
|
* Ström flyter genom ett motstånd $\rightarrow$ elektrisk energi omvandlas till termisk energi
|
|
* Ju större ström, desto mer värme
|

|
* Elektrisk effekt: Hur mycket elektrisk energi som omsätts under en viss tid
|
|
* Enheten för effekt $P$ är watt ($\unit{\watt}$)

## Beräkning av effekt
|
|
|
|
Beror på ström och spänning
|
|
|
|
$ P = U \cdot I $
|
|
$ U = \dfrac{P}{I} $
|
|
$ I = \dfrac{P}{U} $
