Question details

(2.)(50 points)Consider the electrical circuit illustrated in Figure 2 below. Ini tially, both switches Si and S2 remain open. The initial voltage across capacitor Ci is 50 volts with the polarity shown in Figure 2. Ch 5mF (a-)(5 points)Switch Si closes at t 0. Switch S2 remains open. Find the initial current, ica (0+) flowing in the capacitor Ch (b)(10 points)With switch S2 still open and switch Sh still closed, find the current flowing in capaitor Ci for t >0. (c.)(10 points)Using the result of part (b.), find the voltage across the capacitor Ci for t 0. Remember, switch S2 is still open. (d.)(5 points)After a very long time (t oo), switch Sh opens at the same time that switch S2 closes. If vca (0-) 10 volts, find the initial current flowing in capacitor C2 HINT: The circuit uill look like that in Figure 2a. (e)(20 points)What is the final voltage reached on capacitors Cl and C2? Use the circuit of Figure 2a. HINT: One way to do this quickly is to note that charge must be conserved. otherwise, use K. V.L. to solve this problem. 3Q 5Q 100V 0.005F vo (0 vc (07) 0.005F
