ELEC 101, Spring 1998
## ** Homework 4 **

** Date Assigned: ** Monday, February 2, 1998

** Date Due: ** Friday, February 6, 1998

- The Lab 3 assignment is handed out today.
Note that some pre-lab questions are included in the assignment.
You should answer the pre-lab questions in your lab notebook
*before*
coming to lab on Thursday.
I will look at your answers and grade them at the beginning
of lab.
- Design a voltage divider that will produce a voltage
division ratio of 0.5 (that is, the output voltage is
half the input voltage).
The voltage divider should not draw more than 10 mA when the
input is a 10 V source (so the output voltage is 5 V).
Explain your reasoning.
- Please solve problem 1.30 in the text by combining
series/parallel resistors and using voltage dividers.
- Please find the current
*i*,
the voltage *v*_{2},
and the voltage across the 3000 ohm resistor in the circuit below.
Be sure to label the polarity of the voltage across the
3000 ohm resistor in your answer.

- Please do the problem on the back of this sheet,
which is very similar to the temperature sensor application
discussed in class and Lab 3.
