Question

The reverse bias in a junction diode is changed from 8V to 13V, then the value of the current changes from 40μA to 60μA. The resistance of junction diode will be ______.

Options

• 2 × 10⁵ Ω

• 2.5 × 10⁵ Ω

• 3 × 10⁵ Ω

• 4 × 10⁵ Ω

Answer 1

The reverse bias in a junction diode is changed from 8V to 13V, then the value of the current changes from 40μA to 60μA. The resistance of junction diode will be 2.5 × 10⁵ Ω.

Explanation:

As, R_e = `(Delta"V")/(Delta"l")=((13-8))/((60-40)xx10^-6)`

= 2.5 × 10⁵ Ω
