Unformatted text preview: Problem 1 : DC I-V Characteristics (10 pts) Draw the DC I-V characteristics for figures 1-2. (5 pts each) (DC in this case means nothing else than that a particular voltage or current has been applied for a long time such that all transients have died out until we measure the resulting current or voltage respectively) Make sure you label your graph such that the characteristics are completely defined (the shape of curve alone is not good enough) 7.5 [V] I +- V 0.1 [H] 22 [uF] Figure 1. 5 [Ω] 1 [A] I +- V Figure 2.
