Homework 7: due Tuesday (Oct. 19) ENEE204 (Gomez) 1. Exercise in circuit reduction a. (Hint: Assume the infinite ladder has finite input impedance Zin. Then calculate what will be the effective impedance if one more segment is added. Segment means - the basic unit that repeats over and over to make the infinite ladder) b. Replace the resistors with 10 mF capacitors, find equivalent resistance and plot in log- log scale, Zin vs. frequency from 0 to 10 9 Hz. 2. Using Superposition principle , find the current i flowing through the 60 Ω resistor. 3. Solve problem 2 using Thevenin theorem . Use the following procedure. i. Remove the 60 kΩ resistor from the circuit. ii. Replace the remaining circuit by the non-ideal voltage source model. iii. Connect the 60 kΩ resistor to the non-ideal voltage source model and find the current

For the circuit given below, V s (t) = 100 sin(1000t) and i s (t) = 2 cos(1000t). Find the voltage V c (t) across the capacitor using superposition principle . 6. Solve Problem 5 using Thevenin theorem to find Vc(t). Use the following procedure. i. Remove the capacitor, across which you need to find Vc(t), from the circuit. ii. Replace the remaining circuit by the non-ideal voltage source model. iii. Connect the capacitor back to the non-ideal voltage source model and solve for Vc(t). 7. Using superposition principle , find the voltage v indicated in the circuit below, all resistors in kiloOhms....
