Practice question · True or false
The capacitance of a capacitor increases when more charge is placed on its plates.
Hints
- Capacitance is a ratio, what happens to both of its parts?
- Doubling the charge doubles the voltage, leaving the ratio unchanged.
Show the answer
False
Why
False, is fixed by geometry and the dielectric. Adding charge raises in exact proportion, so the ratio is unmoved. Only area, separation or the medium can change it.
