The current delivered by a current source is increased linearly from zero to 10 A in 1 ms time and then is decreased linearly back to zero in 2 ms. The source feeds a 3-kΩ resistor in series with a 2-H inductor (see Fig. 2-24). 

(a) Find the energy dissipated in the resistor during the rise time (W₁) and the fall time (W₂). 

(b) Find the energy delivered to the inductor during the above two intervals. 

(c) Find the energy delivered by the current source to the series RL combination during the preceding two intervals.
