Unformatted text preview: voltage vab(t) = 0. At time: t=0 seconds, switch A closes ; and remains closed thereafter. At time: t=0.5 seconds, switch B closes ; and remains closed thereafter. Calculate and plot (on graphs that are neatly drawn) the voltage vab(t), and the current i(t), as a function of time, for values of time between: t=0- seconds and t= 1 second. How much energy (Joules) is stored in the capacitor at each of the following times: t=-0.000001 second, t=+.000001 second, t= 0.5 seconds, t=1 Switch A (shown open) C= .0002F Vs= 500V Rs = 500 Ω Switch B (shown open) i(t)...
