The Table 1 below shows the voltage a cross a 36μF capacitor from 0s to 23s. Evaluate and plot the current and power against time. i) Determine the equivalent inductance when the switch SI is opened and closed, respectively. ii) If a 20A current flows throught the equivalent inductance during the switch is closed in question i), what is the value of the energy at that moment.
