Diagram1: http://i.imgur.com/StJae.png Diagram2: Close the switch http://i.imgur.com/PnSIH.png What is the current in resistor2? Please show the math. Thank you. [No, it's not a homework problem, I'm just curious.] Some people say it would short out on resistor 2 and current would be zero, but that's supposedly not right. The current becomes some fraction of what it would be if R2 were in series with R1. I am aware of Kirchoff's laws, but this is still stumping me. Thanks in advance.
