Homework Statement
What will be the current flowing theoretically through each resistor this short-circuit case?
Homework Equations
[tex]V=IR[/tex]
[tex]I=V/R[/tex]
[tex]R_{T}=\frac{1}{\frac{1}{R_{1}}+\frac{1}{R_{2}}+...\frac{1}{R_{N}}}[/tex]
For a closed loop, [itex]\sum I_{entering}=\sum I_{leaving}[/itex]
The Attempt at a Solution
My answer: The current through each resistor will be effectively zero. This is because a practically resistance-free path exists (the short circuit) through which essentially all of the current will flow.
The professor's response: Theoretically, the current through the 4-ohm resistor is infinite.
I disagree. How can the current through any of the resistors (4Ω, 6Ω, or 12Ω) be anything other than ~0 A when the current will seek the path of least resistance (the short circuit)?
