PYQ NEET- Current Through A P-N Junction

• NEET 2019:

The reverse saturation current in a p-n junction diode is independent of the applied voltage. This is because the reverse saturation current is the current that flows through the diode when the applied voltage is zero. As the applied voltage increases, the reverse saturation current remains constant.

• NEET 2018:

The current in a p-n junction diode is related to the applied voltage by the equation I = I0(e^(V/kT) – 1). Here I0 is the reverse saturation current, k is the Boltzmann constant, and T is the absolute temperature. If the temperature is increased, the current will increase. This is because the reverse saturation current increases as the temperature increases, and the exponential term in the equation becomes larger.

• NEET 2017:

In a semiconductor, the number of holes is equal to the number of electrons when the semiconductor is intrinsic. This is because in an intrinsic semiconductor, there are no impurities present, and the number of electrons and holes is the same.
