# Electricity — circuits, switches and safety, sentence 13

<!-- .ven lang=en -->
A battery stores chemical energy and pushes electricity around a circuit.

<!-- .vintro -->
**Who acts:** battery · **What happens:** store, push · **To what, where:** chemical energy, electricity, circuit

<!-- .vabout -->
This is a sentence of the lesson «Electricity — circuits, switches and safety» of the world 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 (battery), what happens, when and where, as Mova's frames read it from the tree.
