Question

Answer with either True ir False
(a) From the definition of capacitance, C = Q/V, it follows that an uncharged capacitor has a capacitance of zero.
(b) As described by the definition of capacitance, the potential difference across an uncharged capacitor is zero.

Answer 1

(a). If there is no charge across the capacitor the capacitance will be zero. Therefore, the answer is true.

(b) Let's write the potential difference across the capacitor:

$$V=\dfrac{Q}{C}.$$

As we can see from the formula, if there is no charge across the capacitor, the potential difference across the capacitor will be zero. Therefore, the answer is true.

Answer:

(a) True.

(b) True .
