1) find vc(t) (t > 0) in the circuit below if r = 1 k . 2) find vc(t) (t > 0) in the circuit below if r = 3 k . questions 1) which circuit (r = 1k or r = 3k ) is more damped? 2) is there a relation between the value of r and the damping of the circuit? if so, how are they related? 3) which circuit (r = 1k or r = 3k ) has a smaller settling time? 4) measure the time duration between subsequent zero crossings of the response for the r = 3k circuit. is it what you expected? prelab assignment carry out the theoretical analysis and computer simulation for each of the two problems. + .01 f r 20 mh 5u(-t) v r - vc
