A 5V battery is connected across the points X and Y.

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 $X$.

  1. $\sim 0.86 \mathrm{~A}$

  2. $\sim 0.5 \mathrm{~A}$

  3. $\sim 0.43 \mathrm{~A}$

  4. $\sim 1.5 \mathrm{~A}$


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 $I=\frac{5-0.7}{10}=0.43 \mathrm{~A}$
