Problem
A parallel-plate capacitor has fixed plates, so its capacitance remains constant. If the magnitude of the charge stored on the plates is tripled, quantitatively describe how the potential difference across the plates changes.Intuitive explanation
The key insight is that capacitance is a fixed property of the physical setup—it doesn't change when you alter the charge. Since is always true, if you triple the charge while stays constant, the voltage must also triple to maintain that relationship. This is a direct proportionality: more charge means proportionally more voltage pushing against the fixed capacitance.
