Reverse Characteristics

Using the necessary circuit diagram, show how the V-I characteristics of a p-n junction are obtained in (i) forward biasing (ii) Reverse biasing. How are these characteristics made use of in rectification?

In which one of the following devices the reverse biased characteristics of a p-n junction diode are used?

Which of the following properties are characteristic of lyophobic sols ? 1. low viscosity, 2.high viscosity , 3. reversibility and 4. coagulation by electrolytes at low concentration Select the correct answer using the codes given below:

What are the characteristics of an ideal contraceptive? a. User-friendly b. Easily available c. Effective d. Reversible e. No or least side effects r. No way to interfere with the sexual drive, desire and/ or the sexual act of the user. Cheap

The following table provides the set of values of V and I obtained for a given diode. Let the characteristics alpha be nearly linear, over this range, the forward and reverse bias resistance of the given diode respectively are
