For a circuit shown in the figure, &-12V, R:=42, R2=62, R3=22, Ram12, C1=10 mF, C;-4 mF, C=8 mF. After having been at contact a for a long time, at t=0, the switch throw is rotated to contact b. a. What is the current passing through R4 before the switch throw is rotated to contact b? Why? b. Draw equivalent circuit(s) that can represent the circuit right before the switch is thrown from a to b. c. What are the charges, Q1, Q2, and Q3 stored in C1, C2, and C3 respectively just right before the switch throw is moved from a to b? Please explain your reasoning process clearly and thoroughly. d. Draw equivalent circuit(s) that can represent the circuit after the switch is thrown from a to b. e. What is the current passing through R4 right after the switch throw is rotated to contact b? 1. What is the time constant of this circuit after the switch throw is rotated to contact b? 8. Find the voltages V1, V2, and V3 for C1, C2, and C3 at t-10ms after the switch throw is rotated to contact b. h. What is the current passing through R4 10 ms after the switch throw is rotated to contact b? a Ri
