Question

If the forward voltage in a semiconductor diode is changed from 0.5 V to 0.7 V, then the forward current changes by 1.0 mA. The forward resistance of diode junction will be (A) 100 Ω (B) 120 Ω (C) 200 Ω (D) 240 Ω

Tardigrade Admin · Accepted Answer

Forward resistance =(Δ V/Δ I) =(0.7-0.5/1.0 × 10-3)=200 Ω

Q. If the forward voltage in a semiconductor diode is changed from $0.5 V$ to $0.7 V$ , then the forward current changes by $1.0 m A$ . The forward resistance of diode junction will be

$100 Ω$

$120 Ω$

$200 Ω$

$240 Ω$

Forward resistance $= \frac{Δ V}{Δ I}$
$= \frac{0.7 - 0.5}{1.0 \times 1 0 ^{- 3}} = 200 Ω$
