what should be a simple capacitor question.
Hello,
I have a question I have been pondering for a bit, me thinks it should be simple, but I cannot seem to get it straight.
Imagine two capacitors leg to leg.
each has 10 farads.
Each is charged to 100 volts.
Each should have a charge of 1000 coulombs.
Now we reduce the capacitance of one of the capacitors to 1 farad.
by way of equation Q=VC, and knowing that charge is conserved, we know that this capacitor now stands at V=1000 F=1 C=1
so now we have two capacitors one is at V=1000 C=1 Q=1000
The other at V=100 C=10 Q=1000.
Because of the voltage difference, they will want to equalize. What do they end up at
for V,C and Q?
