LAB 1 (2/2 points) You have a 6-volt battery batter y (assumed ideal) and a 1.5-volt flashlight bulb, which is known to draw
when the bulb voltage is
(see figure below). Design a network of resisto rs to go between the battery batter y and the bulb to give connected, yet ensures that
does not rise above
when the bulb is
when when the bulb is disconnected.
There are two schematic diagrams diagrams below. Please enter the t he network of resistors you've designed into both diagrams. The top diagram is the model when the bulb is connected; the bottom diagram is the model mo del when the bulb is disconnected. Run a DC analysis on both both diagrams diagrams to show that the node labeled labeled "A" has a voltage voltage of approximately approximately less than
in the top diagram diagram and
in the bottom diagram. Please submit your results after the the DC analyses have been run so that the results of the
analyses will also be submitted. Because we will be checking the voltage at node A, you should have an assigned voltage at node A after the DC analysis; otherwise, your submission will be deemed incorrect. Schematic model when bulb is connected:

Hint : use a two-resistor voltage divider to create the voltage for node A. You'll have two unknowns ( determined by solving the two equations for , and one involving
