Question
A half-wave rectifier is a device that takes an oscillating voltage as input and outputs only the positive portion of that input. In one particularly simple type of half-wave rectifier (see the figure (Eigure 1)), the alternating voltage source is changed by using a diode to essentially eliminate current flow in one direction. Doing this forces the output voltage to take only positive values (or a value of zero), even though the input voltage will alternate between positive and negative. The key to the working of a half-wave rectifier is the diode. The standard circuit symbol for a diode a triangle with a line at the point. The point of the triangle corresponds to the n region, so that current flowing in the direction in which the triangle points corresponds to positive current (i.e., current arising from positive potential difference Va across the diode). A diode with positive Va is said to be forward biased. A diode with negative Va is said to be reverse biased. The current-voltage relationship for a diode is given by Figure 1 of 1 in in
Explanation / Answer
Ans:
I = Is (eeVd/KbT-1)
= 10-8(e1.602x10^-19x1.5/1.38x10^-23x300-1)
= 10-8(e58.043478-1)
= 1.6 x1017A
