# Homework Help: Is this a parallel circurt?

Question:
Is this a parallel circurt?

Revelant equations:
None required

Attempt at solution:
I know that a parallel circurt has more than one pathway for the current to flow and has resistors parallel to each other. However in both of the pictures shown, there are two parallel paths but the resistors are not parallel. Is that still considered a parallel circurt then?

Why would the physical orientation of the resistors matter? It's the electrical connections that matter.

It doesn't matter? Then in the 2 pictures, which one would not be?

Do you have a more explicit definition for two resistors to be in parallel -- or in series, for that matter?

You're supposed to tell us that. If two resistors are in parallel, they're connected to the same two nodes in the circuit. For which of the circuits does this hold true?

Same two nodes....

I think maybe it would be the first one because the second has resistors in the same line, which would be similar to a series?

As SammyS said, it's the electrical connections that matter, not how the resistors are drawn.

I'm not sure I know what you mean by that.

Nodes means the point where the current splits right? In the first diagram, the the resistor shares one node with the other. The second one also shares one node.

Is it that in order for it to be a parallel circurt, the electrons from a branch cannot meet the load from the other, therefore the second diagram is not parallel

Circuit B is definitely interesting in the way its drawn, but what if you were to draw a resister in Circuit B where the resistor is in Circuit A, and label it 0 Ohms. Does that help change your understanding of the circuit? Can an electron find a way to move from the voltage source through both resistors and back in Circuit B? Circuit A?
