nice video, did you know that a normal diode also makes light, but is encased in the black plastic, so we don't see it in the end, something I learned not to long ago.
You forgot to mention that LEDs have a forward voltage that is substantially constant , with varying currents .... connecting a voltage source higher than this may result in a HUGE current , burning out the LED ..... The current is normally kept to a safe value with a series resistor .... example : a small blue ( or white ) LED ( Vf 3 Volts ) connected to a fully charged 3v7 Lithium battery WILL INSTANTLY BLOW ... to prevent this , a resistor of 47 Ω to 100 Ω in series will limit the current to about 10 mA , which is safe for the small LED ( tried - n - tested ) ......................

Please take this a strictly constructional criticism. When teaching a basic lesson on how something actually works, it is very important to GET IT RIGHT, even at the most basic level. Your example here fails in several ways. First of all, it simply won’t work as shown. Here’s why: Your “circuit” consists of a BATTERY, DIODE and LED. Let’s break it down to the simplest terms... 1. BATTERY. Not enough voltage. This appears to be a AA - size cell. It even looks like a Duracell “Copper top”. These batteries generate a nominal output of 1.5 volts DC. Not enough for ANY type of LED. All LEDs require more than that. 2 - DIODE. Not needed for this circuit. It actually makes things worse, It is not required for 2 reasons: 1 - You’re using DC, and the LED is already a diode, and 2 - these diodes have a forward voltage drop of about 0.7 volts. So now, the available voltage at the LED is only about 0.8 volts at most. Not enough to light at all. 3 - LED. First of all, LEDs run on CURRENT, not voltage, and that current must be limited to prevent damage to the LED. For the green LED shown here, it is typically 20 to 30 mA at about 2 volts, and “super-bright” green LEDs need at least 3 volts at that current. All you’ve got is only 0.8 volts. No current will flow - it’s not going to light. SOLUTION: Add a 2nd battery (in series) so that you have 3 volts, and replace the diode with a current-limiting resistor, such as 150 ohms or so. If you want to light a super-bright LED, add a 3rd Battery (4.5 volts). The LED will then light up. - Bill V. - Retired electronic design engineer

Great explanation. Very interesting. Thank you
Purana..... Remember hua.... 😊
nice video, did you know that a normal diode also makes light, but is encased in the black plastic, so we don't see it in the end, something I learned not to long ago.
Generally it is made of silicon and emits heat instead of light.
Good teaching
Absolutely Amazing ❤❤ loved the animations and the clarity I got was just wow❤❤❤❤ Thankyou so so much for this incredible video🎉🎉❤❤🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏
Thank you so much sir
Very informative video
Nice information 😊
Nice😊😊😊😊😊😊😊😊😊😊
A very nice video on the topic. I wish the producer be my personal tutor.
Nice explanation. Thank you.
Leds are not made of Si, it gallium arsenic GeAs. Si doesn't emit light
Explained better than my teacher
Let's grow up ✌️ never stop ✋️ learning ✌️ ✋️ 🥳 👍 ✨️ ❤❤❤
New comment new subscriber❤❤❤❤😂😂
is it the resistor that must be install in series with the LED isn't it?
Every thing explained is excellent.. but you forgot to discrib how Photon generate from and emitting when electron pass through..
Nice
Good illustration

What is diode
Super led bulb awesome explanation video. Keep it up. Thank you for the knowledge. ❤
Super
Thank you
That revise my p and n type concept
Then where does recombination process occur
Light emiting diode
Simple but excellent interpretation --- thanks from India.
amazing

Can I convert videos in Hindi for Indian listeners
no he can use ai
If someone sees this content definitely they know english bruh
@@yeahhboi9894 I know they new english but in indian culture some of state student knew only hindi
No,us indians should have better comprehension of English
Hindi speaking only need hindi not the rest
Hey 👋
really helpful
LIGHT OF THE WORLD GOD YAHWEH GIVE LED LIGHT BULB TO SERVICE

یااخی لا اعرف ماذا اقول انا اتیت هنا لکی ارا ال LED واجزاه فقط ولاکن وجت شی اکثر من ذالک و هو کیف یعمل ال دایود انا من وقت طویل اعلم به.هاذا مثل الذی فی ال فیدیو ...ولکن کثر من قنوات تعطی معلومات غیر صحیحه مثلا یقولون الالکترونات ال الموجبول حفرات اله السالب ومن هاذه القبیل ولکن فی هاذا الفیدیو هی الحقیقه .....شکرن کثیرا❤
