Quiescent point (Q point)

a point on the DC load line of a given amplifier that represents the quiescent (no signal) value of output voltage and current for the circuit.

Description : In which region is the operating point stable in tunnel diodes? (1) Negative-resistance (2) Positive-resistance (3) Both negative- and positive-resistance (4) Neither negative- nor positive-resistance

Answer : In Negative-resistance region is the operating point stable in tunnel diodes.
