| Apr 25, 2019 at 23:04 | comment | added | Harper - Reinstate Monica | Meh, there's no such thing as negative resistance. It's an artifice of improperly (IMO) applying Ohm's Law to something non-linear (not resistor-like). If we flip it into conductance, you are saying something has a negative conductance, i.e. its conductance goes below 0 (below total insulator - in other words current flow induces a reverse voltage). Such a device is not a good fit for Ohm's Law. | |

| Apr 25, 2019 at 16:11 | comment | added | Michel Keijzers | Maybe if you see a circuit with two resistors in series (voltage divider), having in the middle 2.5V, a component with negative resistance can be said to 'add voltage' instead of removing voltage... but I leave a real answer to the experts here ;-) | |
