P3.2-29 The voltage across the capacitor in Figure P3.2-29 is  V for

t ≥ 0. Determine the voltage source current i(t) for t > 0.

 

Figure P 3.2-29

 

The current i(t) is the current passing through the 20 resistor.  For the orientation of i(t) shown, we would go from the capacitor to the voltage source, so the equation should be
