What the hell is a 3D circuit?

Maybe something like a resistor cube[

The fact that it can be described in a 2d schematic means that there is no 3rd dimension required to complete it.

how about the one MIT uses?

Fundamentals of Physics by Halliday et al. Will have all of the info you need for intro to circuits and most of what you need for your first year of physics.

 

[JohnCU]

uhh maybe im still drunk and don't know any better but resistors in a delta aren't in series or parallel (depending on the circuit layout)

 

[RESmonkey]

its not a physics class. It's Intro to Electrical and Computer Engineering (circuits class). But theres no fucking textbook!

 

[esun]

Yes. Series means that the current through the resistors is the same. Parallel means the voltage across the resistors is the same. Draw any circuits where any two resistors do not satisfy either of these conditions (should be easy) and you'll have one where the two resistors are not in parallel or in series.

 

[blueshoe]

Yes, resistors can be neither in series nor parallel. Here's the way I'd look at it:

If a resistor is sharing one node (and only one node) with another resistor, they are in series. The same current will be going through these resistors.

If two resistors share two nodes with each other (one node on each side of the resistor) then they are in parallel. Put one finger on one side of a resistor and another finger on the other side of the resistor. If you can follow the wire without lifting your fingers and they end up being across another single resistor, then these two resistors are in parallel.

Circuit

None of the resistors are in parallel. Only R5 and R6 are in series.

This is the textbook that I used in my Intro to Circuits class:

[QuixoticOne]

"The Art Of Electronics" is highly commended.

R2 and R4 aren't in parallel with one another?

I don't know about that.

Now this is coming from an engineering school dropout, but if I were to answer the OP's question I would tell him that resistors are always in parallel, in series, or both. The only time they are neither is if they exist alone without any relationship to a circuit.

how can they be in parallel? they don't have the same voltage/node

R2 and R4 are not in parallel, but I see R4 as in parallel to the R5+R6 series. I see it as an issue of semantics. A whole circuit may not be a simple series or parallel circuit, but each resistor is always in series and/or in parallel to other sections.

R5 and R6 are in series. But I think what you're saying, is something like, a resistor on one side of a huge circuit board, can be said to NOT be in series or in parallel, with another resistor WAY on the other side of the board.

So, R2 is not in parallel with the R3 + R4 series and also the R5 +R6 series?


Many moons ago I did a lab final where I arranged an array of resistors like a wagon wheel with resistors on each spoke and in between each spoke on the perimeter. The goal was to determine the resistance from any two points. All I can remember was the all the resistors were both in parallel and series and the solution wasn't pretty.

 

[Colt45]

tehy're all in series-parallel anyways, point doesn't exist.

wye?

 

[DrPizza]

What if you made a circuit such that there was zero potential difference across the resistor? i.e. two series circuit loops, and connect two points with equal potential between the circuits?

Yes, R4 is in parallel to the R5+R6 series.

But you can't say that R2 is in parallel with R3 + R4. R3 is not in series with R4. R3 is in series with the equivalent resistance of (R5, R6, R5). R2 is in parallel with the equivalent resistance of (R3, R4, R5, R6).

If there is no potential difference across a resistor, it means that the resistor is not connected at one end.

If there is no potential difference across a resistor, it means that the resistor is not connected to a voltage/current source.

Then how do you explain a Wheatstone bridge? Consider a quadrilateral whose sides are composed of equal resistors. Suppose a resistor is placed across one of the diagonals and a voltage/current connects the remaining two vertices. You now have a resistor with a zero potential difference across it, which is (sort of) connected to a voltage or current source.

The above two statements are false.

 

[Gothgar]

Shouldn't this be in highly technical? Or is this too easy for that forum?

You are correct. I should have said:

If there is no potential difference across a resistor, it means that the resistor is not conducting current. It says nothing specifically about its connection.
