Remember to draw equivalent circuits to help with the analysis! R₁ (b) At t = 0, what are the currents in each resistor? (c) For t→∞o, what are the currents in each resistor? R₂ 350 ww (a) At t = 0, what is the voltage across the capacitor? How are the voltages across R3 and R2 related?

Problem 4 In the circuit to the right, & = 1.2kV, C = 6.5 µF, and R₁ = R₂ = R3 R = 0.73 M. With C completely uncharged, switch S is sud- denly closed at t = 0. Remember to draw equivalent circuits to help with the analysis! R₁ - 18 S R₂ R₂ (a) At t = 0, what is the voltage across the capacitor? How are the voltages across R3 and R₂ related? (b) At t = 0, what are the currents in each resistor? (c) For too, what are the currents in each resistor? (d) For t→∞, what are the voltages across each resistor? (e) For t→∞, what is the voltage across the capacitor? (f) Once the circuit has nearly reached equilibrium, the switch is reopened. What is the current in each resistor right after the switch is reopened? The equivalent circuit will be super useful here; note that when we change the circuit by opening the switch, the capacitor is no longer in steady state - do not assume its current is zero! (g) How long after the switch reopened does it take for the current in R3 to drop to half of the value it had immediately after the switch was reopened?
