2. An ideal battery (no resistance) for which V =9 Volts is placed in series with a 100 2 resistor and a 20 mF capacitor in a closed loop circuit, as shown in the figure below. What is the RC time constant? The switch is closed at time t= 0. What will be the current in the-circuit just after the switch is closed? What is the current in the circuit a long time after the switch is closed? Use DESMOS to make a graph of the current in amperes versus the time in seconds, from t= 0 to t = 5RC.

In figure 1, suppose that ε = 69.0 V, R = 250.0 ohms, and L = 0.170 H. Which switch S2 open, switch S1 is left closed until a constant current is established. Then S2 is closed and S1 is opened, taking the battery out of the circuit. Part A: What is the initial current, just after S2 is closed and S1 is opened, then determine the current in the resistor at t = 4.50x 10^-4 s. Part B: What is the potential difference between points b and c at t = 4.5 x 10^-4 s, then determine which point is at a higher potential (b or c)? Part C: How long does it take the current to decrease to half its initial value? Answer in seconds. Thank You for the help in advance!
