Muchas gracias Maestro, saludos de su humilde casa, Sinaloa, México.

The problem with these projects is that NO ONE explains or justifies from a theoretical point of view why they used the resistance value they used and why they chose that dissipation power for the resistor. In this video 82 ohms were used but others use 33Kohms, others 47Kohms and even 100Kohms with dissipation powers of 2W, 3W or 5W. An explanation should be given as to why they used the R they did. Greetings.

You need to calculate using formula Vi-Vled/ I where input voltage is Vi, Vled is forward drop of an led & I is forward current of an led. We can even use a 1 k resistor without any calculation😊

Thanks for comments।Your comments are very valuable for me।

[@peeyushkansal6798]

Can you also explain how 82 ohm resistor value is calculated?

[@YusufChandawala]

Good idea very nice

Tarun ji is it possible to addthis circuit to a multi meter so that direct reading through multi meter is possible ?

[@Golden_unicorn]

Very Good!, does anyone know what the resistor is for? can it be higher wattage resistor? Thanks

[@oslecc100]

can you make a backlight tester or led buld,,using a circuit of long tube light bulb,,thank you❤

[@muddassirsheeraz]

Thanks. Please guide me how to put digital volt meter 2 wires in it?

[@lukasz19884]

Can There be a 91ohm resistor

[@ElectronicaVK]

It's very nice. Can you tell me your thoughts about the led tester that I have made on my channel?

[@shajhanislam4323]

Nice

सर Ac mcpcb पूरी चेक हो सकती है ।

[@amitghosh6966]

We can't test multiple leds connected in series in a 9 watts led bulb Mcpcb as each Led is 9 Volt total 9 leds so 81 volts needed to test all at one go

[@cellibra3117]

what abouth,,the driver of long tube buld led

[@elhatillanodigital5011]

I think there are many important questions without an answer.

18v වලට වඩා ලොකු වෝල්ටෙජ් එකක් එනවනේ.
300v වගේ එනව. ඒ ඇයි. එහෙම එකකින් හදාගන්න බැරිද මේවගේ එකක්

[@apkpka-jb3ho]

රෙජිස්ටර්එක කියේ එකක්ද? වොට් ගාන කියද? කියන්න

[@techtarun77]

Resistance 82 Ohm (Half Watt)

[@ManuelVillamizar-t3k]

De cuanto es la resistecia

[@omarbinetti535]

81ohmios

The video with music is of no use to viewers without telling the commentary and parts what and how you are using

[@utube4waqas]

without dc volt meter there is no befit of this device
