Homework will be due before 5 pm on WEDNESDAYS.They
can be turned in at the desk at the end of the 3-4 lecture on Wednesday
or put into the locked box marked EE42 outside Room 275 in Cory Hall.Homework
solutions will be posted in the glassed-in bulletin board in the Cory 2nd
floor hallway just outside Room 275.

Additional
problems for Assignment No. 2:On
the linked web site “Simple Circuit Demos” go to NODE EQUATIONS
OF RESISTOR CIRCUITS, DEMO 3
Problem
2A.Using nodal analysis (the method
is illustrated nicely there) find the nodal voltages V1 and
V2 assuming that the resistor on the far right has the value
2 KW
instead of 1 KW.(Note:
the solution given may have a minor numerical error in it, but the method
is correct.)
Problem
2B.Now assume that instead you short-circuit
the 1 KW
resistor on the far right (connect a wire across that resistor), leaving
all the other resistor values and the voltage source unchanged.
a.Using
nodal analysis find the current that flows from the positive terminal of
the voltage source.
b.Check
your answer by combining the resistors into a single equivalent resistance
connected across the voltage source.(Give
the value of that resistance.)

3.11; 3.13; 8.5 (Notes: dc steady state means a long time after the battery
was connected – what is VA then?This
circuit has Rs, Cs and Ls together, whose response to transient excitation
we won’t discuss in EE42); 8.21 (in addition to the questions asked, find
an expression for the voltage VA for all times after t = 0 until
the switch is reopened);
Problem
3A:work problem 8.10 with values
R1 = 3000 W,
R2 = 500 W,
L = 10 mH,
and the stated values for i(t).Also,
what is i (t) as t approaches infinity?) |

that the short-circuit current on the solar cell I-V characteristic of
"Fig. 28.2" on p. 7 of lecture notes for 11 March 2002 is -10mA.
What value of load resistance should be connected to extract the maximum
power from the solar cell, and what is the value of the maximum power?
