The discussion revolves around the treatment of a 1 ohm resistor in a circuit analysis problem. Participants explore the reasoning behind neglecting this resistor when calculating the equivalent resistance of the circuit, focusing on current flow and voltage drop considerations.
Participants express differing views on the treatment of the 1 ohm resistor. Some agree that if the current is zero, the resistor can be neglected, while others seek further clarification on the implications of this assumption. The discussion remains unresolved regarding the broader implications of ignoring the resistor.
The discussion highlights assumptions about current flow and the interpretation of circuit diagrams, which may affect the conclusions drawn about the 1 ohm resistor's relevance in the analysis.
Nugatory said:What is the current through that resistor? What does that tell you about the voltage drop across it?
it will go to V0. there is a voltage V0anorlunda said:Current has to come from someplace and go to another. If there was current in the 1 ohm resistor, where would it go?
So you mean if the current doesn't go anywhere after passing through the resistor so we disregard it? we consider the current is equal 0?anorlunda said:No, you are misinterpreting the diagram. Those circles at the ends of the wires near V0 depict the terminals of an open circuit. Zero current goes to V0.

Got it. Thank you, appreciated.anorlunda said:Yes. If we know the current in the resistor is zero, then the resistor can be removed or ignored without changing the circuit.
