What is capacitance?

Explanation

**Step-by-Step Solution:**

1. **Definition of Capacitance**:
Capacitance is a property of a capacitor that indicates its ability to store electric charge. It is defined as the amount of electric charge (Q) that can be stored per unit potential difference (V) across the capacitor.

2. **Mathematical Relation**:
The relationship between charge (Q), capacitance (C), and potential difference (V) can be expressed mathematically as:
