The forward-bias voltage of a diode is changed from 0 . 6 V to 0 . 7 V , the current changes from 5 mA to 15 mA . What is the value of the forward bias resistance?
Correct answer
10
Step-by-step solution
The forward biased resistance of a diode is R = ∆ V ∆ I = 0 .7 - 0 .6 15 - 5 × 10 - 3 R = 0 .1 10 × 10 - 3 = 10   Ω
