You need to connect the ground to your circuit. Just tap on the ground node and tap on the bottom wire of your circuit

Then adjust your resistor to 47 Ohms to light LED’s.

how do you calculate the ohms according to led

how much resistance does led have?

sir why without giving resistance for the circuit Led burns?What is the cause?

That's coz LEDs have a vatiable resistance, trying to keep the voltage across them almost constant, just like a diode.

EveryCircuit LED’s have a nominal working voltage of 2.0V. You have 3 in series so the total drop across them is 3x2 = 6V. They are have a nominal current of 20mA. To calculate your resistor value, with a 12V supply you need to drop 6V across your resistor (to leave 6V across LED’s). From Ohm ‘s law R=V/I=6/0.02=150 Ohms.

Sorry, 300 Ohm.

I think you’ve made component value changes since my first comment:-)
