What are 1) forward bias and 2) reverse - bias?

What happens to the width of depletion layer of a p-n junction when it is (i) forward biased, (ii) reverse biased?

In the following diagram, is the junction diode forward biased or reverse biased ?

(i) Figure shows the input waveform which is converted by a device .X. into an output wavefrom. Mane the device and explain its working using the proper circuit. (ii) Draw the forward bias and reverse blas circuit for the basic component of the device and draw the characterstics. Explain clearly which region of the curve is used in an amplifier.

The dominant mechanisms for motion of charge carriers in forward and reverse biased silicon P-N junction are

A 2V battery may be connected across the points A and B as shown in figure. Assume that the resistance of each diode is zero in forward bias and infinity in reverse bias.Find the current supplied by the battery if the positive terminal of the battery is connected to (a) the point A (b)the point B.

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

With reference to a semi-conductor diode, what is meant by : (i) Forward bias (ii) Reverse bias (iii) Depletion region. (b) An EM wave, Y_(1) , has a wavelength of 1 cm while another EM wave, Y_(2) , has a frequency of 10^(15) Hz. Name two type of waves and write one application for each.

What is the ratio of forward and reverse resistance of p-n junction diode?

The resistance of p-n junction is low when forward biased and is high when reverse biased. Explain.

For the equilibrium AhArrB , the variation of the rate of the forward (a) and reverse (b) reaction with time is given by :
