Hi everyone, I don't know if this could be understood here but I don't have any way of putting the diagram here so I'll try my best to illustrate it as clear as possible I hope it's understandable and please bear with me! If I connect to capacitors, one 1uF and the other 2uF in parallel (no emf drawn in, just a closed box with the 1uF one on the left side and the 2uF one on the right side of the box) with a P.d of 6V across them. In this case, the positive plates of the 2 capacitors are on the same side (top) on the circuit. I can find the total charge in them to be 18uC. But why is it that, when I reverse the plates on the 2uF capacitor, the total charge becomes 6uC? (12uC - 6uC)? I can't understand the concept even after some thinking through. Appreciate any help. Many thanks in advance.
