Question : 5
Total: 26
Graph showing the variation of current versus voltage for a material GaAs is shown in the figure. Identify the region of
(i) negative resistance
(ii) where Ohm's law is obeyed.
(i) negative resistance
(ii) where Ohm's law is obeyed.
Solution:
(i) In DE portion of the graph, the current decreases as voltage increases. Hence, this is the negative resistance region.
(ii) In AC region of the graph, the current increases as the voltage increases. This region follows Ohm's law.
(ii) In AC region of the graph, the current increases as the voltage increases. This region follows Ohm's law.
