Task 2 The electric circuit in the figure below contains a current source driving a series inductive and resistive load with a shunt capacitor across the load. The circuit is representative of motor drive systems and induction heating systems used in manufacturing processes. Excessive peak currents during transients in the input could damage the inductor. Therefore, the equation below is used to compute response of the current through the inductor to a step in the input current to ensure that the manufacturers stated maximum current is not exceeded during start up as per the underdamped system. i(t) = = e 0.599 t (t) Load [0.678 sin (1.3227 t) + cos (1.3227 t)] (1) 2-A) Use Excel to plot i, vs t per equation (1). The range of t should be from 0 to 13 seconds. The range of it is to be chosen adequately by you. Make sure to label all axes, add grid lines, and title your graph.

List the steps for dc steady-state analysis of RLC circuits.
The 'R+LC' circuit shown in figure 1 is an RLC circuit with a resistor followed by a capacitor and inductor in a parallel configuration. Consider R, L, C arbitrary positive constants. R 0000 Figure 1: 'R+LC' circuit (a) Find the differential equation that describes the transient current in the in- ductor. Show all your work (i.e. all the Kirchhoff rules used in the derivation, any relationship among the variables used to get the final result, etc.) (b) What combination of R, L, C will generate i) overdamped, ii) critically damped and iii) underdamped behavior? Let's now consider the case when the transient behavior generates (non-zero) underdamped oscillations. (c) Find the time dependent expression of the current in the inductor.
