In the following circuit the capacitance varies as C = KQ, where K is a constant
equal to 0.5 Farads/Coulomb and Q, the charge on the capacitor in Coulombs.
Determine the current through the circuit and sketch the voltage waveform
across the capacitor (VC) for a step input Vi as shown in figure.

The network shown in figure is
initially under steady-state
condition with the switch in
position 1. The switch is moved
from position 1 to position 2 at t =
0. Calculate the current
i(t) through R1 after switching.
