and/or then) 1. a) The circuit below has three resistors with values R₁-10 S2, R2-20 S2, R3-30 S2, one initially (t-0) uncharged 0.001 F capacitor, and a 30 V battery. Find all the currents at t=0 (right after the switch is closed,) all the currents a long time after the switch is closed (at steady state), and the charge on the capacitor at t→∞o. At time ti, once steady state with the switch close has been effectively reached, the switch is reopened. Find the currents at this time, right after reopening the switch.
