Direction : Read the following question and chooseA. If both assertion...
Assertion: When the base region has a larger width, the collector current increases.
Reason: Electron-hole combination in the base results in an increase in base current.
Explanation:
The given assertion and reason both relate to the operation of a transistor. Let's analyze each statement separately to determine their validity and the relationship between them.
Assertion: When the base region has a larger width, the collector current increases.
- This statement is true. In a transistor, the base current controls the collector current. A wider base region allows more carriers (electrons or holes) to flow from the emitter to the base, resulting in a larger base current. As a result, the collector current also increases.
Reason: Electron-hole combination in the base results in an increase in base current.
- This statement is false. In a transistor, the base current is primarily due to the injection of minority carriers (either electrons or holes) from the emitter into the base region. The combination of electrons and holes in the base region does not directly cause an increase in the base current. Instead, it is the recombination of these minority carriers in the base region that leads to the transistor's amplification function.
Relationship between the Assertion and Reason:
- The reason given does not explain the assertion accurately. The assertion correctly states that a wider base region leads to an increase in the collector current. However, the reason incorrectly suggests that the electron-hole combination in the base is the cause of the increase in base current. In reality, it is the injection of minority carriers into the base region that causes the increase in base current.
Therefore, the correct answer is option 'D' - Assertion is false, but the reason is true.
Reason: Electron-hole combination in the base results in an increase in base current.
