EE 213 – Extra Credit I – 10 points Due Thursday, October 22 nd NOTE: You must make a reasonable attempt at every problem in order to receive any credit. 1. You have a 20 V, a 4 V, and a 9V battery. You need to apply 15 V to a circuit. Can you do it with the batteries you have? How? (use words and/or drawings). 2. You are given an unknown element (see below) with the following I-V relationship: i(v)=6v-4. Is the element linear? Is it active or passive? Explain your answer. (Hint – plot the i-v curve.) 3. For the following two circuits, solve for the required voltage or current
