Physics Question on Semiconductor electronics: materials, devices and simple circuits
A conductor and a semi-conductor are connected in parallel as shown in the figure. At a certain voltage both ammeters registers the same current. If the voltage of the DC source is increased then
the ammeter connected to the semiconductor will register higher current than the ammeter connected to the conductor
the ammeter connected to the conductor will register higher current than the ammeter connected to the semiconductor
the ammeters connected to both semiconductor and conductor will register the same current
the ammeter connected to both semiconductor and conductor will register no change in the current
the ammeters connected to both semiconductor and conductor will register the same current
Solution
If the voltage of the DC source is increased then both conductor and semiconductor registers same current i.e., semiconductor is in forward biased condition and it conducts. So, ammeters connected to both semiconductor and conductor will register the same current.
