Imagine a battery that creates a +9000V Potential difference in respect to ground (The Earth) in it's positive terminal. (The Earth is at 0V in this example)
And a +8992V potential difference in respect to ground in it's negative terminal.
- Suppose we connect this battery to a capacitor with a voltage rating of 8V, Normally it shouldn't exceed the capacitor voltage rating due to 8V potential difference.
First Question: Will this capacitor have a higher capacitance(even a tiny bit more capacitance?) Second Question: In a closed circuit this capacitor will produce only a potential difference of 8V, But if we connect the positive terminal to ground,And the negative terminal to ground, Will the potential difference be much higher?.
