A $5V$ 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 $+ ve$ terminal of the battery is connected to point $X$ .

A 5V battery is connected across the points X and Y . Assume D _ 1 and D _ 2 to be normal silicon diodes. Find the

Options

A $~ 0 . 86A$
B $~ 0 . 5A$
C $~ 1 . 5A$
D $~ 0 . 43A$

Correct answer

D. $~ 0 . 43A$

Step-by-step solution

A 5V battery is connected across the points X and Y . Assume D _ 1 and D _ 2 to be normal silicon diodes. Find the

Here only ${D}_{1}$ will work and we know for silicon diode, potential drop on ${D}_{1}$ will be $0 . 7V$

$I = \dfrac{5 - 0 . 7}{10} = 0 . 43A$
