The reverse saturation current in a p-n diode will _____ with increase of reverse biasQuestion 3AnswerA.remains constantB.be zeroC.decreasesD.increases

Step 1: Break Down the Problem

We need to analyze how the reverse saturation current behaves in a p-n diode when the reverse bias voltage is increased.

Step 2: Relevant Concepts

In a p-n diode, the reverse saturation current ($I_{S}$) is the current that flows when the diode is reverse-biased. This current is primarily due to minority carriers and is generally considered constant over a range of reverse voltages.

Step 3: Analysis and Detail

1. Reverse Bias Behavior: When the reverse bias increases, the width of the depletion region in the diode widens. This reduces the likelihood of recombination of carriers within this region, maintaining a constant flow of minority carriers.

2. Current Characteristics: The reverse saturation current depends on factors such as temperature and the material properties of the diode but is not significantly affected by changes in reverse bias.

Step 4: Verify and Summarize

After considering the behavior of the reverse saturation current under increased reverse bias, we find that it does not change significantly in normal operating conditions. Thus, it remains constant.

Final Answer

A. remains constant
