Q.
A conductor and a semiconductor are connected in parallel as shown in the figure. At a certain voltage both ammeters register the same current. If the voltage of the DC source is increased then the
A) Ammeter connected to the semiconductor will register higher current than the ammeter connected to the conductor
B) Ammeter connected to the conductor will register higher current than the ammeter connected to the semiconductor
C) Ammeters connected to both semiconductor and conductor will register the same current
D) Ammeters connected to both semiconductor and conductor will register no change in the current
Explanation
(c) If the voltage of the DC source is increased then both conductor and semiconductor registers same current ie, semiconductor is in forward biased condition and it conducts. So, ammeters connected to both semiconductor and conductor will register the same current.
