Can we have some hints on the pset 6 problem with the capacitors and resistors?
In this problem, assume that you are in a steady state (capacitors have finished charging, etc.). Remember that in a steady state there is no current flowing through a branch with a capacitor in it. You can ignore the branch with the capacitor when dealing with the voltage drops due to current through the resistors. “Charge flowing through the switch” is charge that goes on the capacitors; so it’s the net charge on the capacitor plates connected to the switch after the capacitors are charged up. Tidbits Many of the concepts we are covering now are important in biology. For example, nerve cells and their actions can be described by circuit elements such as resistors, capacitors, etc. Basically your brain and nerves act like a very complicated electrical circuit.
