Explanation:

When a large forward voltage V1 and V2 are applied to a semiconductor diode, the diode is said to be forward biased. In this case, the current flows easily through the diode, and it is called the forward current.

Forward Current:
- The forward current in a diode is primarily carried by majority charge carriers (electrons in N-type and holes in P-type).
- The current is directly proportional to the forward voltage applied to the diode.
- The relationship between forward voltage and forward current is given by the diode equation: I = Is * (e^(Vf / Vt) - 1), where I is the forward current, Is is the reverse saturation current, Vf is the forward voltage, and Vt is the thermal voltage (approximately 0.026 V at room temperature).

Reverse Saturation Current:
- The reverse saturation current (Is) is the current that flows through a diode when it is reverse biased and a large reverse voltage is applied.
- In an ideal diode, the reverse saturation current is assumed to be negligible (close to zero).
- However, in practical diodes, there is always a small amount of reverse current that flows due to minority charge carriers and other factors.
- The value of the reverse saturation current is typically very small, on the order of microamperes (10^-6 A) or even smaller.

Given Conditions:
- V1 = V2 (large forward voltage applied to the diode)
- The value of the reverse saturation current is to be determined.

Solution:
- Since V1 = V2, it implies that both diodes are forward biased with the same voltage.
- Therefore, the forward current flowing through each diode will be the same.
- Using the diode equation, we can write: I1 = I2 = Is * (e^(Vf / Vt) - 1)
- Since the forward currents are the same, we can equate the equations for I1 and I2:
Is * (e^(Vf / Vt) - 1) = Is * (e^(Vf / Vt) - 1)
- Canceling out the common terms on both sides, we get:
e^(Vf / Vt) - 1 = e^(Vf / Vt) - 1
- This equation is satisfied for any value of the reverse saturation current (Is).
- Therefore, the value of the reverse saturation current can be any non-zero value, including 0.5 A.

Conclusion:
- The value of the reverse saturation current is not uniquely determined by the given conditions.
- It can be any non-zero value, including 0.5 A.
