College of Engineering Department of Electrical Engineering And Computer Sciences B.E. BOSER Problem Set 1 Solutions EE42/100 Spring 2008 1. a. Use Kirchoff’s Voltage Law (KVL). v x + " v 1 = 0 v x = v 1 b. v x = v 1 = " 3.4 V 2. a. Use Kirchoff’s Current Law (KCL). i x + i 1 = 0 i x = " i 1 b. i x = " i 1 = " 1.2 μ A 3. a. 3 nodes b. In our nomenclature, all circuit elements are "branches" with terminal connected to wires. In this scenario there are 4 branches in this circuit, one for each circuit element. We will also accept 3 branches if you used the methodology discussed in discussion sections. c. Use Kirchoff’s Current Law. i x + i 1 + i 3 = 0 i x = " ( i 1 + i 3 ) d. i x = " ( i 1 + i 3 ) = 2.8 A 4. a. Use Kirchoff’s Voltage Law. (KVL) v 1 " v x + v 2 = 0 v x = v 1 + v 2 b. Use Kirchoff’s Voltage Law (KVL) v y + v 2 = 0 v y = " v 2 c. v x = " 4 mV v y = " 4 mV 5. Use Kirchoff’s Current Law
