Question
Graph showing the variation of current versus voltage for a material Ga As is shown in the figure. Identify the region of
(i) negative resistance
(ii) where Ohm's law is obeyed.
Solution
(i) DE is the region of negative resistance because the slope of curve in this part is negative.
(ii) Where Ohmâs law is obeyed - AB. BC might also be applicable to this particular category.
