Answer 1

Silicon diode is in forward bias.
Hence across diode potential barrier
$Δ V = 0.7 v o l t s$
$I = \frac{V - Δ V}{R} = \frac{3 - 0 . 7}{2 0 0}$
$= \frac{2 . 3}{2 0 0} = 11.5 m A$

Answer 2

Silicon diode is in forward bias.

Hence across diode potential barrier

Δ V = 0.7 v o l t s

I = \frac{V - Δ V}{R} = \frac{3 - 0 . 7}{2 0 0}

= \frac{2 . 3}{2 0 0} = 11.5 m A
