Question

Can Capacitors be negative?

Answer 1

Explanation:

1. The capacitance of the capacitor is the ratio of the amount of electric charge stored on the plates of the capacitor to the voltage.
2. Mathematically express as: $C=\frac{Q}{V}$
3. Where $C$ is the capacitance, $Q$ is the charge stored in the capacitor, and $V$ is the voltage.
4. Therefore according to the above expression, the capacitance will be negative whenever the net voltage across material changes in the opposite direction.
