Equivalent resistance in circuits

Click For Summary
SUMMARY

The discussion centers on calculating equivalent resistance in circuits, specifically focusing on two parallel resistors with an equivalent resistance of 0.6 ohms. It is established that this equivalent resistance can be placed at the nodes where the original resistors (1 ohm and 2 ohm) were located without affecting the overall equivalent resistance of the entire circuit. The key takeaway is that the placement of the equivalent resistance does not alter the total resistance calculation.

The top two resistors are in parallel, so their equivalent resistance is 0.6 ohms.

But if you were to draw the equivalent circuit, where do we place this equivalent resistance?
can it be placed either where the 1 ohm or 2 ohm resistors used to be?
would it affect my answer for the equivalent resistance of the whole circuit?

Don't forget about the "k"! :smile:

The two parallel resistors are attached to two distinct nodes. The equivalent resistance of those two resistors will be attached to the same two nodes.

would it affect my answer for the equivalent resistance of the whole circuit?
No.
