Referring to the figure. The switch S is in position 1 initially and steady state
conditions exist from time t = 0 to t = t

_{0}. At t = t_{0}, the switch is suddenly thrown into position 2. The current I through the 10K resistor as a function of time t, from t = 0 is (in mA) _____________.(Give the sketch showing the magnitudes of the current at t = 0,
t = t_{0} and t = $$\infty$$ )
