Which one of the following statements is 'WRONG' regarding LED?
Which one of the following statements is 'WRONG' regarding LED?
Show Hint
The brightness of an LED can be controlled through the current.
Updated On: Oct 1, 2026
- LED's have long lifetime if properly manufactured.
- Colours produced by LED's do not fade out.
- LED's are energy efficient.
- Brightness of light emitted by LED cannot be controlled.
Show Solution
The Correct Option is D
Solution and Explanation
Step 1: Look at what controls brightness:
More forward current means more electron-hole recombination and more light.
Step 2: Conclusion:
So brightness can be controlled, which makes statement D the wrong one.
Final Answer:
The wrong statement is D, option (D). \[ \boxed{\text{D}} \]
More forward current means more electron-hole recombination and more light.
Step 2: Conclusion:
So brightness can be controlled, which makes statement D the wrong one.
Final Answer:
The wrong statement is D, option (D). \[ \boxed{\text{D}} \]
