How can negative resistance generating power be explained qualitatively .
I saw in some basic circuit theory books tat in a parallel LC circuit , the initial energy
will make it oscillate .But this energy is soon dissipated as heat by the leakage resistances in L & C. A negative resistance is introduced then to cancel out the resistance there, thus producing sustained oscillations..
If this is possible , then we can make every lossy substance into a lossless one by adding a series negative resistance so tat it cancels the series resistance.Then superconductors won't be required i guess ...which has a very low resistance tending to zero...
