Wael by D1 = t³ – 2t² with W measured in [mJ]. The voltage across Device 1 is shown in Figure 2. a) Find an expression for the power delivered by Device 1. Your expression should be a function of time. b) Find the current i (t). Make a neat plot of i(t) for t< 8[s]. c) Determine the time intervals during which power is delivered by Device 1, and when it is absorbed by Device 1. Consider only t<8[s].
