Homework 8: due Tuesday (Nov. 8, 2005) ENEE204 (Gomez) 1. For the following circuit I s1 (t) = 10sin(1000t), I s2 (t) = 20cos(1000t) and I s3 (t) = 10 cos(1000t). Solve the circuit using nodal analysis and find the voltages across all the current sources. 2. Solve the following circuit using Nodal Analysis and use the results to find the voltage V across the 20 resistor indicated by ‘v’ in the circuit. 3. Solve the following circuit using a. Nodal Analysis and b. Mesh Analyis. In each case, use the results to find the current i through the 30 resistor.
