Preliminary Laboratory (Prelab) Work
Complete the following tasks in the space provided below for the circuit shown in Figure 2.
1.
Use voltage division to compute the phasor voltages VR and Vc assuming nominal values of R = 1000[2], C = 0.01[u], and
a cosinusoidal time-domain source voltage signal given by equation 5 below. Voltage division must be used to receive any
credit. (10 points)
equation (5)
Vs(t) = VRMSCOS(ct + 0) = 5cos(@t + 0) = 5cos(62832t + 0) = 5cos(62832t) [V]
=VRMSCOS(2лft + 0) = 5cos[2л(10000)t + 0] = 5cos[2л(10000)t] [V]

Please explain in detail. My answer for the first question is 15/2.
I am more confused about how to do the graphing part and figure how long it will take to reach its final value.
Thank you, I will like this.

- This is the 3rd time i'm asking this. SOLVE THIS AND FIND V0 , the last answer i was given is -2V which is not even one of the listed options. the listed options are: 12V,4V,24V,6V. first answer given to me was 4V but after i simulated on ltspice albeit i'm not sure if i simulated correct i got a different answer and when i solved it myself i got a different answer. this is my last remaining question. PLEASE SOLVE CORRECTLY AND PROPERLY. NODAL ANALYSIS IS BEST TO USE HERE. IT IS AN IDEAL OP-AMP. SIMULATE USING LTSPICE AND GIVE ME FINAL ANSWER IF POSSIBLE AS THAT IS ALL I CARE ABOUT NOT THE PROCESS. THANK YOU.
