Question

2) Shown below is a c R2 = 7 Ω, R3 = 24 Ω, R4 = 10 ircuit with two switches. Si and S2M = 15 V, V.-5 V, V,-20 V, Rı = 15 Ω . 25s2 C,200F v -,,I -R, Г 2:0 start atp sition A. This creates two dependent circuits. The left circuit with only resistors '5 V-15A)(T)-YAG).2ov-ocharges the capacitor C, through resistor Rs with battery Vs(the capacitor is initially The switch 1 will start in the on/closed pasition, and switch 2 (a two-position switch) will Rı, R2, and Ra and batteries Vi and V, and the right circuit which is a circuit that simply uncharged!) : 27-u Determine the current through Rt, R2, and R3, and the voltage drop across R1, R2, and Rs a. rijif': Ri5z-3+R220 b. Describe the voltage drop across the capacitor at the start (t -0) and after waiting for a ng time t ), Switch 1 is now turned off/opened and Switch 2 is now moved to position B. This effectively 5V)-()F 2removes the branch with Vi, V and Ra, the branch with Ri, and the branch with Vs from the circuit. This creates one new central loop 15V-22 IS30 c. Determine the current through Ra, Ra, and R; immediately after the switches are moved to B (t circuit without a battery! hink about what the charged capacitor does immediately when connected to a the current through Rs, R.i, and R: after a long time after the switches are moved (What happens to a charged capacitor after a long time in a circuit witho battery? Do not over think this!!!! How long (how many seconds) after changing the switches will it take for the capacitor to be at half of its original charge? e. 5V-2212 53 5V 22 302 D -31 ISV-2 2 4.29A 2.
