Q. A $5 V$ battery is connected across the points $X$ and $Y$ . Assume $D_{1}$ and $D_{2}$ to be normal silicon diodes. Find the current supplied by the battery if the $+ v e$ terminal of the battery is connected to point $X$ .

$\sim 0.5 A$

$\sim 1.5 A$

$\sim 0.86 A$

$\sim 0.43 A$

Here only $D_{1}$ will work and we know for silicon diode, potential drop on $D_{1}$ will be $0.7 V$
$I = \frac{5 - 0.7}{10} = 0.43 A$
