Consider the rc circuit shown in figure 3. assume a pulse source as shown in figure 2 with ton = 100 microsecond, and von = 1 volt. derive an expression for the current i(t) flowing clockwise in the single loop circuit. obtain expressions for the voltages across the resistor and the capacitor (in the direction of assumed current flow). write the matlab code to plot these two voltages in a single plot as functions of time from 0 to 2 ton.
