# Batteries, circuits and how electricity flows, sentence 1

<!-- .ven lang=en -->
Push the switch on a torch and you close a gap in the loop, so the bulb lights; push it again and the gap opens, and the light goes out at once.

<!-- .vintro -->
**Who acts:** you, bulb, gap, light · **What happens:** push, close, light, open, go out · **To what, where:** switch, torch, gap, bulb

<!-- .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 (you, bulb, gap, light), 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): R6-punct-agree ×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.
