For the circuit below, assume that the current i L (t) is 6 A and the voltage v c (t) across the capacitor is 30 V, just before the switch opens. (a) Draw a frequency (i.e. Laplace) domain version of the circuit for t , taking initial conditions into account. (a) The conversion to the frequency domain involves replacing the battery by 18/s (see middle of page 635 for an example of this), and replacing each of the storage elements by...
