Voltage and parallel capacitor distance

Click For Summary
SUMMARY

The discussion centers on the relationship between voltage and the distance between parallel capacitors in a circuit. It is established that while increasing the distance between fully charged capacitors can theoretically increase voltage, connecting a battery introduces a constant voltage that overrides this effect. Kirchhoff's Voltage Law is highlighted as a crucial principle, confirming that the voltage across the circuit remains constant despite changes in distance. The equation V = Efield x distance does not apply in this scenario due to the influence of the battery's constant voltage.

Assuming the long parallel capacitors to be fully charged and no resistance. So if you increase the distance between two capacitors in a circuit the voltage increases between them. But why is it when a battery is connected to the capacitors in the circuit, increasing the distance won't change the voltage between them?

V= Efield x distance so I'd think V would increase. Am I wrong to assume E is the same at both distances?

I don't think you're saying what you mean.

However, the answer is that the battery supplies a constant voltage. Look at Kirchhoff's Voltage Law.
 
I think I'm saying what I mean lol. It doesn't make sense?

Ah Kirchoff rule, I forgot about him. I see the voltage would then have to be equal since Vloop=0. But I still don't see why V= Efield* Distance doesn't apply in this capacitor circuit? Hope that sounds better.
