1. The problem statement, all variables and given/known data We start with a 2.50 μF capacitor connected to a power supply set to a voltage of 9.30 V. Then we increase the voltage on the power supply by 3.00 V. Now what is its capacitance? 2. Relevant equations Q=ΔV*C 3. The attempt at a solution The answer is 2.5 μF still, but WHY doesn't the capacitance change when the voltage changes?
