Total Capacitance in a circuit?
In the diagram shown to the left:
https://wug-s.physics.uiuc.edu/cgi/courses/shell/c...
C1 = 3.4 μF,
C3 = 3 μF, and
V = 15 V.
a) Calculate the equivalent capacitance of all the capacitors.
In the circuit shown to the right, each capacitor has a capacitance of 10 μF. The battery has a potential difference of 10 V between its two ends.

a) What is the total capacitance between the top and bottom wires of this circuit?
I know how to add parallel and series capacitors, I am just struggling with understanding these circuits (like what is in series and what is in parallel) The drawings, if you look, are confusing!

one very big ambiguity, where the two wires cross over, just below C3, is that a connection or a crossover?
For a connection, there should be a dot.
For a crossover, a loop.
With neither, can't tell which it is, and I don't want to solve it two ways.

Ok, so you can do the maths, good. But there is a skill which isn't taught directly, but absolutely necessary, that is how to redraw a circuit schematic into a functional diagram. So do that, start by reducing parallels to equivalents.
