I have the following definition:

"two or more elements are in series if they exclusively share a single node and consequently carry the same current."

Does this mean if three elements share only a single common node then they are in series? How about the three resistors in the Wye network configuration as shown here https://www.allaboutcircuits.com/textbook/direct-current/chpt-10/delta-y-and-y-conversions/? Are they in series?

Thank you.

no

 

How about this,

If three elements share only a single common node, are two of the three elements in series?

Thanks.

no

did you notice the part about elements in series having the same current passing though them?

if you have three branches, then the current will come in using branch one, then split into two currents, the two currents will leave the node using branch two and branch three.

No. That's a sloppily worded definition.

It can be patched by just referring to two elements only. If you have more than two elements in series, you can inductively build up that they are all in series from the basic two-component definition.

The definition I use is that two components are in series if they must carry the same symbolic current. It doesn't matter if they share a node or not. For instance, a fuse and a switch are in series even if, between them, there are ten lightbulbs in parallel.
