Which type of biasing gives a semi-conductor diode very high resistance?

An n-type semi- conductor is

Avalanche breakdown in a semi conductor diode occurs when

Two conducting spheres of radii r and 3r initially have charges 3q & q respectively. Their separation is much larger their radii. If they are joined by a conductor of high resistance, the force between them will :

Assertion: In reverse biased condition a p-n junction diode does not conduct. Reason: In reverse biased condition a diode has zero resistance.

What type of semi-conductors is produced when silicon is doped with arsenic?

The graph shown in the figure represents a plot of current versus voltage for a given semi-conductor. Identify the region, if any, over which the semicondutor has a negative resistance.

Two identical cells of emf 1.5 V each joined in paralllel provide supply to an external circuit consisting of two resistances of 7 Omega each joined in parallel. A very high resistance voltmeter reads the terminal voltage of cells to be 1.4 V. Calculate the internal resistance of each cell.

With reference to a semi-conductor diode, what is meant by: Reverse bias

What happens to the resistivity of semi-conductors with the increase in temperature?
