Resistance is omnipresent in electronics. A few materials (super conductors)
lose their resistance at fairly low temperatures,
and all materials lose it completely at absolute
zero. However; at normal temperatures.
most (conducting) materials obey Ohm's law,
but some show characteristics of negative
resistance. Are these breaking Ohm's law?
And what good is negative resistance?
