Question
Assuming in forward bias condition there is a voltage drop of 0.7 V across a silicon diode, the current through diode $D_{1}$ in the circuit is
$\_\_\_\_$ mA . (Assume all diodes in the given circuit are identical)
Options
A.20.15
B.11.7
C.17.6
D.18.8
Solution
$\ 12 - 0.3 \times 10^{3}I - 0.7 = 0$
$${\frac{11.3}{0.3 \times 10^{3}} = I }{37.66 \times 10^{- 3}\text{ }A = I }$$Current through diode $D_{1},I_{1} = I/2$
$$I_{1} = 18.83\text{ }mA$$
