# A Capacitor Has Capacitance C. is this Information Sufficient to Know What Maximum Charge the Capacitor Can Contain? If Yes, What is this Charges? If No, What Other Information is Needed? - Physics

ConceptCapacitors and Capacitance

#### Question

A capacitor has capacitance C. Is this information sufficient to know what maximum charge the capacitor can contain? If yes, what is this charges? If no, what other information is needed?

#### Solution

No. This information is not sufficient. Since the charge is proportional to the potential difference across the capacitor, we need to know the potential difference applied across the capacitor.

q ∝ V ⇒ q = CV

Here, q is the charge, V is the potential difference applied and C is the proportionality constant, i.e. capacitance.

Is there an error in this question or solution?
