Hey listen , in this example u have same gnd but in mt project thw 9v is thw main power source , and i have an arduino as the secondry input as your duracell battery but they both have different gnd what to do now?
Well... In this case you are using the transistor more like a diode.. even without the first battery it would turn on, since you connected it to the positive of the Led!.... U need to connect it to the negative of the Led to work like a transistor!
That led is actual lit in the LOW state. I learned that you're supposed to connect the VCC to an LED and then to a resistor and finally to the collector. The other VCC connects to a resistor and then to the base. Lastly, the emitter gets grounded. I believe this is backwards.
The circuit built in the video is an emitter follower which does not switch the transistor between on and off states. It merely sets the emitter voltage to follow the voltage at the base. To work well as a switch, the circuit should be capable of amplifying both voltage and current, so you should use a common emitter circuit where you will find the load connected to the collector.
Yes, you can use. But you have to use a resistor to lower the voltage. If Collector and Base both have same voltage, then transistor will not switch on. But if you apply lower voltage at a base(using a resistor), it will work.
If the current flowing through the LED or transistor exceeds a certain limiting current value (different for different types), the components can get damaged. So to prevent that from happening, we use a resistor (in series) to control the flow of current through them.

To limit current going in the base emitter junction because it is also a diode. It is similar to using a current limiting resistor with an led. The resistor at collector side is for limiting the current through led.
In base, we need resistor because, if we dont use resistor, base and collector will be at same potential, so transistor will not work. If voltage at base is lower than voltage a collector, it will work properly.
10 years later, and you're still helping the boiz out! Thank you so much
Thank you! your video angle is very nicely adjust so I am able to figure out which wire goes to which slot. Really appreciated.
Thank you. I've watched dozens of youtube videos and I can honestly say that I've learnt more in your 4 minutes than i have in others.
very true
true bro...im very much confused in this dude
Thank you sir. You have given the best explanation I have seen in the last 3 years on how to hook these up! Thank you. 😀
@Harshit Saxena WV still at it
can u please give the circuit diagram for it
Bro finally after days of searching I found your video and it helped me a lot
Easy to learn 👍Thanks for giving this such a clear explanation bro🙏
Excellent explaination
Thnx sir g i was working with my project,and it was not getting troubleshooted...thanx a lot sir g
Hey listen , in this example u have same gnd but in mt project thw 9v is thw main power source , and i have an arduino as the secondry input as your duracell battery but they both have different gnd what to do now?
Can I trigger the base of bc547 at 1.5?
How about 0.8v?
The best simplest useful video
Well... In this case you are using the transistor more like a diode.. even without the first battery it would turn on, since you connected it to the positive of the Led!.... U need to connect it to the negative of the Led to work like a transistor!
Very informative
How can a single led glowing with 9v battery while led is only 2.3v
What things do you use here to drop down the voltage for led
can i use Lm7824 as a switch?
thank you bro it really helped me with my investigatory project in physics....
Is that 2N3904..???
Isme kitne volt ke ye components use kiye hai plz tell me
how much volt supply trigger the 547transistor..????
which transistor is tht
Thank you there ...
transistor ko jis ma put kia ha usa kia kahtay ha ??
ty bro
You deserve much more subscribers
thanks sir.
very nice thanking

Can anyone please tell that How Duracell's are attached by battery connector?
THANK YOU SIR. NICE VIDEO FOR OUR PROJECT
You can just in plug the power
What is the transistor number ur using?
Balan SP use BC 547
Amazing my friend ♥♥♥♥♥
Nice to meet you ♥♥♥♥♥
Best wishes for you ♥♥♥♥♥
Keep it up ............. ♥♥♥♥♥

To work well as a switch, the circuit should be capable of amplifying both voltage and current, so you should use a common emitter circuit where you will find the load connected to the collector.
Sir, you can power the transistor with same power supply
Yes, you can use. But you have to use a resistor to lower the voltage. If Collector and Base both have same voltage, then transistor will not switch on. But if you apply lower voltage at a base(using a resistor), it will work.
Every electronic guy in youtube are from india
Why resistors are required ?
If the current flowing through the LED or transistor exceeds a certain limiting current value (different for different types), the components can get damaged. So to prevent that from happening, we use a resistor (in series) to control the flow of current through them.
@@atharvasathe9649 ohh kk thanks
Circuit pls
Can the base of the transistor be powered by the same 9V battery instead of those Duracell batteries?
Yes, you can use. But you have to use a resistor to lower the voltage. If Collector and Base both have same voltage, then transistor will not switch on. But if you apply lower voltage at a base(using a resistor), it will work.
Tq sir
transistor is pnp??
Npn
Give circuit diagram for better understanding
What you can give its circuit diagram
Yee white wali plate ka kya name h???
Luvkush Thakur
Bread board
It is breadboard.
Can u make a Model for the topic "Transistor as an amplifier "..plzz😣
rememeber pin name as city in tamilnadu callled coimbatore know as cbe (collector base and emmiter)
Please reply Any1
why we need resistors in base and Collector
To limit current going in the base emitter junction because it is also a diode.
It is similar to using a current limiting resistor with an led.
The resistor at collector side is for limiting the current through led.
In base, we need resistor because, if we dont use resistor, base and collector will be at same potential, so transistor will not work. If voltage at base is lower than voltage a collector, it will work properly.
Hello sir truth table
resistant value?
he mentioned 1k.
1k
pls give circuit diagram
Then why don't we use a switch
Idk
*New sub added*
This is wrong method
👌👌👌👌👌👌👍👍👍👍👍yes it works
😂😂
Ye curcuit glt h
amazing english
GFF
Its not working properly
Waste of time it is not working 100percent
Please send circuit diagram
