Consider the junction diode as ideal. The value of current flowing through AB is

  1. \( 10^{-2}\text{ A} \)
  2. \( 10^{-3}\text{ A} \)
  3. \( 0\text{ A} \)
  4. \( 10^{-1}\text{ A} \)

Correct answer · Option 1

\( 10^{-2}\text{ A} \)

Explanation

The diode is forward biased as \( +4\text{ V} \) is at p-side and \( -6\text{ V} \) is at n-side. Current \( I = \frac{V_1 - V_2}{R} = \frac{4 - (-6)}{10^3} = \frac{10}{1000} = 10^{-2}\text{ A} \).
