DIRECTIONS: Answer all 10 questions. It’s 100 points. Do all questions in the blue book
provided. This is due on Tuesday Morning, January 2, 2007, at 7:50 AM. DO NOT PLACE
THIS EXAM IN MY MAILBOX; hand it to me in person.

4. You have plugged in a string of 24 IDENTICAL Christmas lights into a 120 V source.
You test the current around one bulb and record the value as 0.5 A. If the string is
connected in SERIES, find RT, PT, and the voltage drop, resistance, power dissipation,
and current of the single light on that strand.
5. Refer to Page 140, figure 4-40. Find VT, RT, IT, PT, and the values of M1 and M3 in the
diagram.
