Sir circuit me resistir selection kase karen or circiut me konsa capicitor lagana ha ya transistir selection kase karen matlab circiut kasse bany ispe video bnay plz bohot log ko yahe problem ha
Calculation kar saktey hai. but resistor jyada power ka lagega, Pahley 4 diode kaa rectifier lagao, phir {220-20}/10mA = 20K, power loss in resistor 10mAX200= 2W, So 20K, 5W kaa resistor lena hoga. shock bhee lagegas touch karney per. Step down transformer laganey per resistor less watt kaa lagega.
for 6V led 0.5W can we use 5V supply? is it be on maximum brightness? I wonder if it needs a resistor to limit the current for preventing to drain extra amps (in 6V it should be 0.083 mA since the P is 0.5 and in 5V it would be 0.100 amps) or it will not even be lighted up...
Sir very good video just a question do i have to divide the current through the resistor or the led's current with voltage and same question with the power what i have to multiply with the resistor voltage drop led's current or the current through the resistor please please please please please please please answer

I have a problem with the clculation: 1) If supply voltage is 9v then the resistor will be R = 9-3/0.02=300 but if we try to find the forward voltage from R then why we get negative value? If R=450 then 450=(9-V)/0.02 and V = 9-9 = 0v. So does it mean that if we use a 450 ohm resistor with 9v battety then output voltage to the LED will be zero volts?
@@GKAgrawal2 But 0.02A is the load current and a load current can vary depending on the type of load. Say we have 0.02A LED and a 450ohm resistor then how we will calculate howmuch will be the forward voltage if we connect them in series with 9v battery? As per the formula R=(Vs-Vf)/I, Vf=Vs-RI and we get Vf=9-(450*0.02) = 9-9 = 0V. That means that the LED will not glow but practically when I use 450 ohm resistor any LED glows! Why?

On manufacturers site and internet.

With 450 ohm resistor, current will not be 20mA. Current will be less.
@@GKAgrawal2 But 0.02A is the load current and a load current can vary depending on the type of load. Say we have 0.02A LED and a 450ohm resistor then how we will calculate howmuch will be the forward voltage if we connect them in series with 9v battery? As per the formula R=(Vs-Vf)/I, Vf=Vs-RI and we get Vf=9-(450*0.02) = 9-9 = 0V. That means that the LED will not glow but practically when I use 450 ohm resistor any LED glows! Why?
.02A LED means, you can flow upto to 20 mA. if you connect 470 ohm, then current gloe has to be calculated.
