I watched two of your videos. Your theory and practical are very beautifully explained. Keep it up. I did my post graduation with specialization in electronics in 1975 and still have passion for electronics. Your contribution is excellent. 👍❤
Variable resistance apne aap me 1 voltage divider hi hota hai Output pe power transistor laga k high current le sakte ho But i don't recommend aise sirf voltage divider se supply nahi banti
Brother I am from Bangladesh.. Your videos are awesome😍. Please make a video about resistor calculation of transistor at various load( speaker,,,led,,motor)
Sir, how did you calculated value of current without knowing the value of resistance connected in series???? Please explain !!!.........is it the current we required in this circuit???
It depends on the value of resistor. If you take a small value resistor, it will work like a short circuit. In conclusion, if you connect a resistor, it will act as a resistive load. Resistors dissipate power in form of heat, that we also call voltage drop across it. The voltage that is been dropped acrossed it, is dissipated in form of heat. In case of LED, the power dissipation is in form of light. Therefore, we can see it. I hope it helped.
Thanks for making video ,its very helpful to we but sir On paper foter side calculation not showing properly beacause of English line showing on screen...each video same issue occurs .
you can use a NTC thermistor (Negative Temperature Coefficient) which is a passive device works as an electrical resistor whose resistance is very high at low-temperature value.
thanx a lot for sharing i tried as u describe but the resistors got heat.... i want to know why the resistors get heated???? plz help me and guide me...
@@TEKNOISTIX according to the voltage divider calculator app i got the value of resistors and connecting two different resistors with each others and put on supply and check the output volts with multi-meter, did not use any kind of load but the resistors are getting heat.... i think there is no short circuit...what is the reason of heating????
@@TEKNOISTIX sir mera matlab voltage divider may lage voltage say hai Quki jab hum R1, R2 resistance ka Maan nikalte Hain to hamme R1,R2 ki value milti hain or ye confirm nahi ho pata ki resistance ohm may hai ya kiloohm may Agar aapne aise he koi video banaye Hai to kripya link send kare
Sir, I want control voltage using a 10K potentiometer, Vin=12V DC, and Vout= (between 0v-5v). So, I need a resistance R1, to drop the voltage in order to produce Vout = from 0v to 5v from the potentiometer. But I am unable to calculate the R1 resistance value. Please help me in this.
Ap bina current nikale hi voltage pta kar sakte hai formula o/p voltage = total voltage (source voltage) /total resistance ×resistor which across find voltage
Instead of R2 if we use R1, what will be the result? You please explain that why consider Only R2? Vice versa if we suppose R2 is R1 and R1 is R2? Then the result will be same? Please reply ,you didn't cover this in it. Is this a rule that positive side resistor is always R1 and negative side resistor is always R2 ???
Sir , first calculate the forward voltage of the led ....then put the value in formula to calculate required current ...--- power = voltage * current.. in your case power is 5 watt....then apply ohm's law ---- Resistance = (6 volts - led's forward voltage)/ current.......
For voltage divider you need to fix one resistance and then you can calculate another one You can take any other value also then can be calculated accordingly
Supply voltage ko pin 1 and 3 par connect kardo potentiometer ki And 2nd and 3rd se output le lo Potentiometer ko rotate karke output adjust kar sakte ho

Sir, how did you calculated value of current without knowing the value of resistance connected in series???? Please explain !!!.........is it the current we required in this circuit???
I wish you were one of our college lectures sir
Thanks 😊
Am already teaching in a college
ease upload videos on voltage multiplier with diodes and capacitors and if possible mosquito killer bat circuit.
Well explained.
If we connect +ve and -ve of battery with resistor, will it drain the battery or short circuit?
It will drain the battery
In above circuit battery's both terminal connected with 2 resistors will drain the 12v battery. is it true?
It will drainnthe battery if no load is connected
If you connect the load current will flow across the load
It depends on the value of resistor. If you take a small value resistor, it will work like a short circuit. In conclusion, if you connect a resistor, it will act as a resistive load. Resistors dissipate power in form of heat, that we also call voltage drop across it. The voltage that is been dropped acrossed it, is dissipated in form of heat. In case of LED, the power dissipation is in form of light. Therefore, we can see it. I hope it helped.
