How to make a Wireless AC Voltage Detector || Wireless Tester || SKR Electronics Lab

Make your Own Wireless AC Voltage Detector.
In this video, we'll show you how to build a simple yet effective Wireless AC Voltage Detector circuit using only two BC547 NPN transistors, one 100K resistor, one LED, and one 3.7V battery. This circuit can detect the presence of AC voltage in a circuit without requiring direct contact with the live wires.
⏺️ How it Works ? 🤔
The working principle of this circuit is based on the fact that the voltage applied to the base of the first transistor can be used to control the voltage level at the collector of the second transistor. When AC voltage is applied to the base of the first transistor, it acts as an amplifier to increase the voltage level of the signal. The second transistor further amplifies the signal and sends it to the LED circuit. The LED lights up when AC voltage is detected, and turns off when there is no AC voltage.
🔘 Circuit Diagram is given in the video so watch the whole video without skipping.
⏺️ Required Components :
1. BC547 Transistor × 2
2. 100K Resistor
3. Red LED
4. 3.7v to 5v Battery

Nice Idea

[@Inventor129]

Great video sir ...God bless u

[@skr_electronics_lab]

Love you bhai ❤️

[@VinodSharma-pt5gr]

Very nice idea bro

[@AjayPatel-lt7bq]

Very nice video sar 👌👌👌👌👌

[@skr_electronics_lab]

Thanks 😊

[@badgaming7634]

Bro kitna ka resistor chaiye plz name batao

[@hackshub3116]

Can i use 5473 transistor instead of bc 547? Both same or not?

[@shashiji27]

बहुत सुंदर
धन्यवाद
क्या हम इस टेस्टर में बज़र भी लगा सकते हैं यदि हाँ तो उसका भी वीडियो या सर्किट भी बनाएं और दिखाएँ

[@skr_electronics_lab]

Ok I will try

[@evilgaming981]

Npn transistor BC 547 iske bdle c947 use krr skte Hai Kya??

[@r.d.suhas0515]

Tomorrow is science day bro please reply

[@kamleshkumaryadav5648]

Very nice

[@skr_electronics_lab]

Thanks

[@gauravmandave5317]

How much price all this compnent

[@mukeshbouri3204]

Is it really work bro plz tell me

[@RamKumar-sw3lj]

दो तार में अगर एक भी सही होगा चेक करने पर भी ये टेस्टर सही बताता है

Bro ye 12v car battry pr kaam lrega

[@ElectronicaVK]

The one I do on my channel does the same job, but mine is very small.

[@r.d.suhas0515]

Bro can we use fevistick instead of glue gun

[@skr_electronics_lab]

Yes

Ok bro I will try

100 k resistance ka watt kitna hai

[@skr_electronics_lab]

1/4watt

[@zeeshanahmad8943]

Bhai mujhko shoulding iron lena hai toh kon sa thek rahega price 45 wala 125 wala kon sa lein 25 watt main

[@skr_electronics_lab]

125 wala accha hoga

[@abdulgafarnadaf6153]

We can veri the resistor ( 1k , 2.2k , 4.4k etc )

[@skr_electronics_lab]

But why bro ?

[@ShankarExperiment]

Bhai aapka thumbnails circuit diagram galat hai bhai Apne galat thumbnails circuit diagram dala he❤❤❤❤

[@skr_electronics_lab]

Yes bro , because agar me real circuit diagram dal dunga Thumbnail me to log video na dekh kr Thumbnail ka screenshot se hi bana lenge

[@skr_electronics_lab]

Video ke andar real hota hai

[@pradeepsharma5510]

Bhai wire solder nahi ho raha hai kaise solder karna chahiye is per video bannao

[@skr_electronics_lab]

Konsi wire me solder nhi ho raha hai?

[@pradeepsharma5510]

Please comment bro

[@sureshgoyal9751]

Resister ke dono points ko kis prakar se solder karana hai,
Please reply ,
यदि नीचे लिखे सब्सक्राइबर्स को मालूम हो तो मुझे समझाने का कष्ट करें

[@Voltageboyhaidar777]

Resister me + - nahi hota hai to aap kisi bhi side se solder kar sakte hai

Check the connection bro

काम ठीक से नहीं कर रहा है
