Negative resistance From Wikipedia, the free encyclopedia Jump to navigationJump to search Fluorescent lamp, a device with negative differential resistance.[1][2] In operation, an increase in current through the fluorescent tube causes a drop in voltage across it. If the tube were connected directly to the power line, the falling tube voltage would cause more and more ..
