capacitance depends on electric charge.
Mechanism: Capacitance measures how much charge a component stores per volt applied.

electric charge causes electric field.
Mechanism: Every electric charge sets up an electric field in the space around it.

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 2 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 → 5 → 16 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

What builds on this
1 concept build on this directly, 1 in total, across 3 disciplines.

Check yourself
A quick check against a common misconception. Nothing is scored — picking the tempting-but-wrong answer just flags an idea worth revisiting.
Which statement is correct?
Rubbing two objects creates new electric charge.
Rubbing only transfers existing charge from one object to the other; total charge is conserved. One ends up negative exactly as much as the other ends up positive.
Look for: Learner thinks friction makes charge appear from nothing.

Concepts that look related but are not yet connected here — candidates for a connection to reason about, not established links.
Electric charge comes in two kinds, called positive and negative. Like charges push apart and opposite charges pull together. Rubbing a balloon on your hair moves charge and makes the balloon stick to a wall.
Charge is a conserved property of matter, carried in whole multiples of the elementary charge e. Charges create electric fields that exert forces described by Coulomb's law, and moving charge is what we call electric current.
