A full wave rectifier circuit with diodes $\displaystyle \left(D_1\right)$ and $\displaystyle \left(D_2\right)$ is shown in the figure. If input supply voltage $\displaystyle \mathrm{V}_{\text {in }}=220 \sin (100 \pi t)$ volt, then at $\displaystyle t=15 m s e c$
Official answer
From NTA’s final answer key for this paper.
(1)
$\displaystyle D_1$ is forward biased, $\displaystyle D_2$ is reverse biased
(2)
$\displaystyle D_1$ is reverse biased, $\displaystyle D_2$ is forward biased
NTA’s answer key accepts either.
