Alright so I am studying this now and started this assigment but I dont understand it completley:
Alright so as far as I got it, I should chose a junction (in this case I chose A) and for that junction, only first closest capacitor in each branch that goes to that junction, his charge will be added into sumation with a sign thats turned to that junction,
and then I should write Voltage equations like this:
1. Choose a direction
2. Going through a loop, the sign of a voltage is the sign out of which the current from direction leaves.
So:
Q1 + Q3 = 0
E1 = Q2/C2 + Q1/C1
-E2 - E1 = - Q3/C3
And for U3 I got it correctly, its 36V.
for U2 and U1 values should be
U2 = 8 V
U1 = 4 V
but I got something else... So can someone please explain to me what mistakes am I making while writing equations either for charges
or voltages :/ ?
