That depends on the points you are interested in. There is no parallel or series connection for all setups in this sketch.anthonych414 said:

2) The same goes for wires: A wire that wiggles around the page and jumps over other things is theoretically the same as a point! What matters is what it connects together, and all those connections can be thought of as being to a single point.
3) You are free to rearrange the diagram in any way you want so long as you don't disturb the topology (what is connected to what). You can stretch or shrink wires, reorient components, slide connections along wires, etc., to your heart's content if it will make the circuit more obvious to you.
In your first circuit, which I've reproduced here:
Note the points I've marked C and D in red. There's no reason why that wire has to be that long. And there's no reason that those resistors connected to it have to have the connection points where they're shown. The same goes for the wire at the bottom and its connections.
Why don't you redraw the circuit, bringing the connections of those resistors to the center of those those wires? (Slide the connections of the 4 and 12 Ohm resistors to the middle of the wire CD. Do the same for the pair of resistors at the bottom with its wire. Can you spot any parallel or serial opportunities now?
For the second circuit, try to imagine what it would look like if your were to "pick up" node d and pull it over to lie between nodes a and b. Don't be afraid to bend and twist the wires or reorient the components. Just don't break any connections!
Note that not every circuit will present you with opportunities of parallel or series components to simplify, no matter how you rearrange the diagram. In those cases there are other methods you will have to apply, which I'm sure you'll be learning about soon.
Parallel connections refer to a circuit where the components are connected in a way that allows current to flow through multiple paths simultaneously. In contrast, series connections refer to a circuit where the components are connected end-to-end, creating a single path for the current to flow through.
To identify if a circuit is in parallel or series, you can observe the paths of the current. In a parallel circuit, the current splits into multiple paths, while in a series circuit, the current flows through a single path. Additionally, you can also test the voltage and current at different points in the circuit to determine its connection type.
Parallel connections offer several advantages, including increased current and power, more reliable operation, and easier maintenance. In parallel circuits, if one component fails, the others will continue to operate, ensuring the circuit's overall functionality.
Series connections have some drawbacks, such as a decrease in voltage and power, the potential for one failed component to disrupt the entire circuit, and less stability compared to parallel connections. Additionally, series circuits may require more complex circuitry and have higher resistance, resulting in less efficient operation.
Yes, a circuit can have a combination of parallel and series connections, known as a series-parallel circuit. These circuits offer the benefits of both connection types, allowing for increased current and reliable operation. However, they can also be more complicated to design and analyze compared to circuits with a single connection type.
