question 1 please

ame: Last four digits of student ID: now all your work leading up to the final solution/answer (no work = no credit). 1. Use the following values for the components in the circuit in Fig. 1: R = 5, R. = 150, R = 1 K, C = 1.0 uF, and V = 12 V. (15) The switch is moved from position "a" to "b" att = 0. a. Draw the equivalent circuit for t < 0 and compute V.. b. Draw the equivalent circuit fort 20 and compute the current i(t). C. Compute the voltage, Va(t), fort > 0. a t=0 b Ro 2 c. RR van Figure 1. 2. Use the following values for the components in the circuit in Fig. 2: R=400 , XL = 400, Xc = -2400 282 V. Compute i(t) and V(t). and Vac (10)

Answer 1

ER Ra=56, Roalsh, R=1ks, C=1.out, and V-12V. @ Equivalent circait for & Co O from kirchhoff Z c > Voltage law. I I . Rat. IR & uv since voltage acroes R and c is same. so.
