Assuming in forward bias condition there is a voltage drop of 0.7 V across a silicon diode, the current through diode D1 in the circuit is ____ mA. (Assume all diodes in the given circuit are identical)
A
11.7
B
18.8
C
20.15
D
17.6
Explanation
Total current: i = (12 − 0.7)/(0.3×10³) = 11.3/300 ≈ 37.66 mA Current splits equally: i₁ = 37.66/2 ≈ 18.8 mA
