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

Consider the junction diode as ideal. The value of current flowing through AB is
A $10^{-2}$ A
B $10^{-1}$ A
C $10^{-3}$ A
D 0 A

The answer is A.

Solution

An ideal forward-biased diode has zero resistance.


The ideal diode is forward biased, so $I = \frac{V_A - V_B}{R} = \frac{4 - (-6)}{1000}$ A
$I = \frac{10}{1000} = 10^{-2}$ A
