In a PN-junction diode - Vidyadip

MCQ

In a $PN-$junction diode

✓
The current in the reverse biased condition is generally very small
B
The current in the reverse biased condition is small but the forward biased current is independent of the bias voltage
C
The reverse biased current is strongly dependent on the applied bias voltage
D
The forward biased current is very small in comparison to reverse biased current

✓

Answer

Correct option: A.

The current in the reverse biased condition is generally very small

a
(a)In forward biased $PN-$junction, external voltage decreases the potential barrier, so current is maximum. While in reversed biased $PN-$junction, external voltage increases the potential barrier, so the current is very small.

A particle projected from origin moves in $x-y$ plane with a velocity $\vec{v}=3 \hat{i}+6 x \hat{j}$, where $\hat{i}$ and $\hat{j}$ are the unit vectors along $x$ and $y$ axis. Find the equation of path followed by the particle

The International Avogadro Coordination project created the world's most perfect sphere using Silicon in its crystalline form. The diameter of the sphere is $9.4 \,cm$ with an uncertainty of $0.2 \,nm$. The atoms in the crystals are packed in cubes of side $a$. The side is measured with a relative error of $2 \times 10^{-9}$, and each cube has $8$ atoms in it. Then, the relative error in the mass of the sphere is closest to (assume molar mass of Silicon and Avogadro's number to be known precisely)
