(a) In Figure Q.3(a), the switch has been in position "a" for a long time, and it is switched to "b" at 1 = 0 s. ve(t) is the voltage across the capacitor, C, and vo(t) is the voltage across Ro. (i) Determine ve(0') and ve(0'). (ii) If it is desired that vo(0) = 20 V, what should be the suitable value of R,? With the value of Ro as in (ii), determine the expression of ve(t) for t>0s in terms of C, and hence determine C so that ve = 0 V when t = 4.64 ms (iii) (i.e., ve (0.00464) = 0 V). Using R, as in (ii), obtained the expression of vo(t) for t> 0 and determine the value of vo (1) when t = 4.64 ms. (iv) 6 Q 10 2 2Ω 15 V C R. Vo (t) Ve (1) $7.5 2 24 V Figure Q.3(a)
