http://forum.allaboutcircuits.com – Hi all: I am just starting Circuit Theory and am taking Physics 2 concurrently. As such, I am new to many of the subjects and terminology used in the book I am using and am finding reading it quite a challenge (For those interested, it is The Analysis & Design of Linear Circuits by Thomas/Rosa/Toussaint). Anyway I am having trouble figured out a particular problem on our first problem set: 1-14: An incandescent lamp absorbs 100 W when connected to a 120-V source. An energy-efficient compact fluorescent lamp (CFL) producing the same amount of light absorbs 16 W when connected to the same (Embedded)
