The diode shown in the circuit is a silicon diode. The potential difference between the points A and B will be

Calculate the current through the circuit and the petential difference across the diode shown in figure .The drift current for the diode is 20 mu A .

Statement-I : Diode lasers are used as optical sources in optical communication. Statement-II : Diode lasers consume less energy.

An ideal diode should pass a current freely in one direction and should stop it completely in the opposite direction. Which is closer to ideal-vacuum diode or a p-n junction diode?

In the given circuit the current through Zener Diode is close to :

Assertion:Diode is a combination of n-type and p-type semiconductors. Reason: The solar cell is an efficient photo-diode used for conversion of light energy into electrical energy .

Assuming that the junction diode is ideal the current through the diode is :-

From the Zener diode circuit shown in figure, the current through the Zener diode is

In the circuit shown if current for the diode is 20 muA , the potential difference across the diode is

A diode can be used as
