# Batteries, circuits and how electricity flows, sentence 14

<!-- .ven lang=en -->
A power station turns big machines that push electricity along wires on tall pylons to our homes, at very high voltage.

<!-- .vintro -->
**Who acts:** power station, big machines · **What happens:** turn, push · **To what, where:** big machines, electricity, high voltage

<!-- .vabout -->
This is a sentence of the lesson «Batteries, circuits and how electricity flows» of the physics course of Mova's primary school. The page gives its syntax tree — a dependency tree in the style of Universal Dependencies — and its pragmatics clause by clause: who acts (power station, big machines), what happens, when and where, as Mova's frames read it from the tree.

**The tree:** Mova annot: Rust (en) → Haiku 5.5 (medium, Batches API) patches; gates UD 2.18; agreed by treeagree rules (Stanza, Trankit, spaCy trf): R5-strong ×1, R7-rel-agree ×1. **The frames** are read from the tree by Mova's frames reader (`prag`) when this page is built, the lesson read in order, so a pronoun may be resolved from an earlier sentence.
