Engr 5A F.Brewer Homework #2 Due Wed at beginning of class. Reading: Handout Ref: Ma 5a Text, ECE 2a text 1. Consider an endless network of resistors, each 1 , as shown below. Find an exact expression for the resistance of the entire network from point a to b. Hint: assume the resistnace is X -- then andd a new section in front. .. what will be the new resistance? 2. Find the resistance from point a to b in the following infinite network using superposition of two currents. (This can be done in your head once you see the trick. ..) 3. Find the general solution for the following equation: 4. Find a solution for the voltage across the capacitor in the reader given that the Battery is re-
