3. The diagram in Figure P2.1 shows the electrical connection of two devices. The current ix and the voltage vx are shown. Assume that the current ix(t) is a current made up of the flow of electrons. Assume that Device 1 Device 2 ix(1) = (42[mA]e¬7S[s*}r – 25[mA]); for t >0, and i(1) vr(t)=3.75[V]; for t> 0. Figure P2.1 a) Is Device 1 in the active or passive sign relationship with respect to ix and vx? b) Which way are the electrons moving through Device 2 at t = 1[ms]? c) Which way are the electrons moving through Device 1 at t = 5[ms]? d) What is the power absorbed by Device 2 for t> 0? e) Are the electrons gaining or losing energy as they move through Device 1, at t = 3[ms]? f) What is the energy delivered by Device 2 for the time period 0
