In resistor,when input applied voltage increases it causes electric current also increases through in it because of ohms law,this property is called positive resistance of element or circuit.but here is negative resistance property,if applied voltage increases it causes decreases electric current through in it,it is called negative resistance of a element or circuit.
EX: uni junction transistor(UJT),tunnel diode,gunn diode, thyristors, IMPATT, magnetrons etc.
*Advantages of negative resistance:
1.used in oscillators. UJT oscillator,gunn diode oscillator.
2.mainly used in high frequency oscillators in microwave applications.
