voltage causes electric current.

Mechanism: Voltage drives current: a difference in electric potential pushes free charges through a conductor, just as a height difference makes water flow.

Structural role & consequence

Interpreted from the current atlas graph — what the connections mean, not just how many there are.

  • Directly enables 1 concept; following enables/causes relations, 2 concepts are downstream across 3 disciplines.

    structural · Follows only enables/causes dependency edges — not general relatedness.

  • Currently dark in the atlas: no key date stored · 3 of 3 of its relations lack claim-level evidence.

    atlas representation · Describes the current Thinking OS representation, not the state of the world.

  • Structural neighbourhood: 3 → 15 → 33 concepts reachable within 3 hops.

    structural · Structural reach — being reachable is not the same as being understood.

  • All 3 of its relationships stay within its own discipline — a field-specific concept in the current atlas.

    structural · Structural graph analysis — not a claim of importance, causation or history.

Strengths & constraints

Constraints

  • Evidence coverage currently thin in the atlas — few of its relationships carry claim-level evidence. atlas representation
  • No dated history stored — the atlas records no key date for this concept. atlas representation

Conditions

  • Read structurally — most of its relationships carry no external evidence yet, so claims here are graph-derived. structural
