Problem:
The current in and the voltage across a 5 Hinductor are known to be zero fort <= 0. The voltage across the inductor is given by the graph in fort >= 0. A. Write the expressions that describe the current i(t) in piece-wise linear representation in suitable intervals. Find the current in the inductor at t2 s. B. Derive the expressions for the inductor power and energy. Use the passive sign convention. Sketch the current, power and energy waveform...

question 27 and figure 9.43
I think 10u(1-t) means 10 (for t<1) and 0
(for t>1)
then, I can't remove this current source because it
continuously make 10micro A
(at t=500ms, t=1.002ms)
I don't know what's wrong now..
