Thought i was crap at electronics. you could just use a suitable zener with a current limiting resistor?

Thank you your all chanalls

It will heat or what if a massive current has decreased to 5v and I use this circuit as a phone charger. Thankyou

حسنت .. الصراحة ابداع حقيقي شكراً 👍

The way this works is to first reduce the current with 100 Ohms before the Zener diode clamps voltage to 5.7V, then silicon diode such as 1N4001 is further dropping the voltage by 0.7V to make it 5V on theory. There are two problems with this approach. First, the current is very low (i=V/R=12V/100 Ohms=120mA). The second problem is that the voltage drop across a silicon diode changes with the current flowing through it. You can already tell that output is 5.19V, not 5V. If you really want to make this circuit works, use 10 Ohms resistor(~1.2A), but it has to be a high wattage resistor. Also, Zener and has to be able to handle that current as well. Even after supersizing those components, the voltage will vary depends on the load. Just use a 7805 voltage regulator.

Dc to dc? Is a wastle of component use a normal resistor an a dz of 5v.

Thank You for this video 👍

Normally you would simply use a 7805 regulator or a 5v zener, Or even a combination of resistors. SO, if you explain what you are doing with those components then people might prefer it, otherwise it does seem like a waste of components.

What a pointless waste of diodes.This is a bridge rectifier used on DC. So one of the 1N4007s is permanently reverse biased (the one with its cathode to the + supply). It can simply be removed. Replace the Zener (with anode to +) with a bit of wire. It's forward biased so is just acting as a 0.6V voltage drop. Replace the other 1N4007 with another bit of wire, again, it's permanently forward biased so is just dropping 0.6V. Replace the 5.7V Zener with a 5.0V as the 0.7V is just to compensate for the drop across the useless forward biased 1N4007. You end up with a 100Ω resistor in series with a reverse biased 5.0V Zener across the supply, with 5V taken from the junction of resistor and cathode of the Zener. Saved 3 diodes.

12 v dc to 9 v dc... for this what value should be for resistor???

Sir how to drop ampere current let says 12v 10a to 12v 2A or 5V 2A

Bol ke bhi btaya yaar full details ke sath

Very nice

How do change this for 3v dc out please.

How many ampere ?

احسنت .. الصراحة ابداع حقيقي شكراً 👍

It is not correct way of converting but you will get 5 v . But diodes are heated too. It not convert realy in 5v it short the voltage more than 5v . You can't use it in your circuit . It gives 0.14 amp of current.

This five volt can be used as mobil cheger. But how much mili ampairs ? Waiting fir ur reply

Sir ye kitna AMP out karte hai

Es circuit pr aisi ek sath kitni led ko laga kr chala skte h

Ampere bhi reduce ho jayenge kya

12v battery rupees ?

nice video thanks😘👍✌😘👍✌😍

Este proyecto funciona, si da los 5V, pero quiero encender un swicth de 5 o 8 puertos, en dispositivo se prende, pero no funcionan las conexiones...!!!

Tolong buatkan casan 5volt 1 amper untuk kegunaan dan keperluan hp samsung, apakah bisa ? Jika bisa tolong buatkan tutorialnya ya ?

10 watt solar me chla ga bta do ji

1 ESA ek divais banana h darwaja khulte hi light on ho jaye

7805 laga de to bhi chalega

Great waste of parts in order to run an LED off a half dead 12v battery.

phone charger hoga

Me ajudem quero converter de 12v 9ah para 6v 9ah como faço??????

can i use 1n4007

If we got Ziner diode with a straight resistance, would it lead to the same result?

Saya mau nanya mas... Saya punya power mobil 12volt tp saya beli 15 volt apakah itu boleh di pakai mas.....???

can it give me 5v to 12v

Nice info 👍, thank you

dude instead of all this crap just use a 7805 you will get 1 amp of current unlike this circuit which is in the milliamps

Kalau gak ada pakai dioda 100om 50v bisa?

Can this sistem with diodes support 4 Amp.?

Bisa utk ngecas hp bang?

12v to5v 10a 20 wat canverter keese banata he

Não falou do resistor

Mantap

Katanya zener 5,7 volt !!! kenapa di layar multitester 5,19 volt ????????

🌹🌹🌹

Kua isse phone 📱 charge hoga

Gosto muito do seu canal 👏👏👏👏

Zener diode heat ho raha hai😭😭😭😭😭😭😭😭😭

Joss. Hadir indonesia

Not working

Bahut low voltage

Oke tolong 2 banget kasih tau ya

Ha Ha ... Another brilliant Indian "electronics - expert" showing how NOT to do it. We had once one "electronician" with all kinds of Indian "diplomas" working for the IT department. He was a real waste and ended up putting 220V on a lan cable resulting on frying a dozen of PC's and several switches. Now, we hired a German IT guy and since 5 years everything runs as smooth as one can wish. My advice (as IT manager) ... Do NEVER think of employing people coming with Indian university "diplomas". These are good guys, but when it comes to problem solving, they are a real waste of time and money.

Useless low Amp voltage, Disliked video
