The answer must match the answer hint. Thanks Problem IIA In the circuit indicated in Figure IIA -(a), a load element (R ohm) is energized by a current source that varies with time as illustrated. a. Deduce the wattage W = (Wi + Wi) corresponding to power supplied to the load over the total period of T sec to T). Express the answer as a function of time in terms of the charge transferred to the load by the source in each interval of time (Ans hint: W1(t) = [(21m/T) x qi(t) x t x R, qi= (2Im/T)xt2 in the interval of time: t 0 to T/2; W2(t) -?, q2 = ?] b. Calculate the total energy expended in the load over the time period T second. (Ans hint: Integrate W(t) over the time intervals) c. Assuming that Vx represents a current-controlled voltage-source (CCVS), what is its possible d. Suppose the circuit Figure IIA -(a) is modified to that in Fig. II.A -(b). Determine the total charge transferred from the source over the period T seconds. (with Wi in the interval, t 0 to T/2 and W2 in the interval, t T/2 X use in practice?
