1. The problem statement, all variables and given/known data The switch has been open for a very long time, and then we close it. In the instant right after we close the switch, assuming that R1[PLAIN]http://loncapa.mines.edu/adm/jsMath/fonts/cmmi10/alpha/100/char3E.pngR2[PLAIN]http://loncapa.mines.edu/adm/jsMath/fonts/cmmi10/alpha/100/char3E.pngR3[PLAIN]http://loncapa.mines.edu/adm/jsMath/fonts/cmmi10/alpha/100/char3E.pngR4, [Broken] what is the total current through the circuit? 2. Relevant equations I=[PLAIN]http://loncapa.mines.edu/adm/jsMath/fonts/cmmi10/alpha/100/char0F.png/(R1+R3+R4) [Broken] 3. The attempt at a solution It's multiple choice, and the "relevant equation" is the correct answer, but why? So capacitors essentially act like wires when fully charged and breaks when charging (let me know if I have those backwards). So, the question is, what do inductors act like when a switch is open and closed?
