Assertion : Photodiode and photovoltaic cell are based on the same principle.
Reason : Both use same method of operations to work.
both assertion and reason are true and reason is the correct explanation of assertion.
both assertion and reason are true but reason is not the correct explanation of assertion.
assertion is true but reason is false.
both assertion and reason are false.
Solution
Assertion: Photodiode and photovoltaic cell are based on the same principle.
This statement is true. Both photodiodes and photovoltaic cells are based on the principle of the photoelectric effect, where incident light generates electron-hole pairs in a semiconductor material.
Reason: Both use same method of operations to work.
This statement is false. While both devices rely on the photoelectric effect, their methods of operation are different:
- Photodiode: Operates in reverse bias and is used to detect light by measuring the photocurrent.
- Photovoltaic cell: Operates in zero bias (open-circuit) and is used to generate electrical energy directly from light.
Conclusion:
The Assertion is true, but the Reason is false.
