Plain-English Meaning
Capacitance measures how much charge a capacitor stores per volt of potential difference.
Keep charge, field, potential, and current distinct. That single habit fixes a large fraction of electromagnetism errors.
Deeper Explanation
Capacitance measures how much charge a capacitor stores per volt of potential difference.
Worked Example
Problem: A capacitor stores 60 μC of charge at 12 V. Find its capacitance.
- C = Q/V = 60×10⁻⁶ / 12 = 5×10⁻⁶ F = 5 μF
Result: 5 μF
