B EE 215 Fall 2018 Homework Assignment #5, due, Monday, November 19th, at the beginning of class Note the due date for homework assignment #5 Problem #1 A voltmeter with a resistance of 100 kΩ is used to measure the voltage vab between points a and b as shown in the circuit below. (a) What is the voltmeter reading? (b) What is the error in the voltmeter reading if the percentage error is defined as [(measured - actual)/actual] x 100% ?

Problem #2 Find the Norton equivalent circuit with respect to terminals a and b in the circuit shown below.

Problem #3 (a) Find the Thévenin equivalent circuit with respect to terminals a,b for the circuit shown below by finding the open circuit voltage and the short circuit current. (b) Solve for the Thévenin resistance by removing the independent sources. Compare your result to the solution you determined in part (a).

Problem #4 This is interesting because it is a great summary problem to solve using your favorite technique. Also, you’ll probably need to use matrices. Find v1, v2 and v3.

Problem #5 The op amp in the circuit shown below may be considered to be ideal. Calculate the following: (a) va (b)

v0 (c) ia

(d) i0

Problem #6 Find i L in the circuit shown below. The op amp is ideal....
