Consider the junction diode as ideal. The value of current flowing through \(AB\) is :
- $10^{-2} A$
- $10^{-1} A$
- $10^{-3} A$
- $ 0 A$
The Correct Option is A
Solution and Explanation
Diode Forward Bias Calculation
In the given problem, the diode is in forward bias, and we need to calculate the current \(i\) using Ohm's Law.
Ohm's law is given by:
\(i = \frac{\Delta V}{R}\),
where:
- $\Delta V$ is the voltage across the resistor (the difference between the voltage across the diode and the supply voltage),
- R is the resistance of the resistor.
Substituting the given values:
\(i = \frac{\Delta V}{R} = \frac{4 - (-6)}{1 \times 10^3}\)
Now, calculating the voltage difference:
\(i = \frac{4 + 6}{1 \times 10^3} = \frac{10}{10^3}\)
Finally, we get:
\(i = 10^{-2} \, A\)
Conclusion:
The current flowing through the diode when it is in forward bias is 10-2 A.
