Question:
A $5 \mathrm{~V}$ battery is connected across the points $\mathrm{X}$ and $\mathrm{Y}$. Assume $\mathrm{D}_{1}$ and $\mathrm{D}_{2}$ to be normal silicon diodes. Find the current supplied by the battery if the +ve terminal of the battery is connected to point $X$.
Correct Option: , 4
Solution:
Here only $D_{1}$ will work and we know for silicon diode, potential drop on $\mathrm{D}_{1}$ will be $0.7 \mathrm{~V}$
$\mathrm{I}=\frac{5-0.7}{10}=0.43 \mathrm{~A}$
