Referring to the figure. The switch S is in position 1 initially and steady state conditions exist from time t = 0 to t = t0. At t = t0, 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 = t0 and t = $$\infty$$ )
