Consider the following statements $\mathrm{A}$ and $\mathrm{B}$ and identify the correct answer:
$A$. For a solar-cell, the $I-V$ characteristics lies in the $IV$ quadrant of the given graph.
$B$. In a reverse biased $p n$ junction diode, the current measured in $(\mu \mathrm{A})$, is due to majority charge carriers.
- A$A$ is incorrect but $B$ is correct
- BBoth $A$ and $B$ are correct
- CBoth $A$ and $B$ are incorrect
- ✓$A$ is correct but $B$ is incorrect
Answer: D.

Answer: C.
View full solution →A logic circuit provides the output $Y$ as per the following truth table :
| $A$ | $B$ | $Y$ |
| $0$ | $0$ | $1$ |
| $0$ | $1$ | $0$ |
| $1$ | $0$ | $1$ |
| $1$ | $1$ | $0$ |
The expression for the output $Y$ is :
- A$A \cdot \bar{B}+\bar{A}$
- ✓$\bar{B}$
- C$B$
- D$A \cdot B+\bar{A}$
Answer: B.
