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 tve terminal of the battery is connected to point $X$.
Correct Option: , 3
Solution:
(3)
Since silicon diode is used so $0.7$ Volt is drop across it, only $D_{1}$ will conduct so current through cell $I=\frac{5-0.7}{10}=0.43 \mathrm{~A}$
