In an online circuit simulator, I was observing the power of a resistor along with the heat produced in the resistor.
When a voltage of +9v is applied across a resistor of 10 ohm connected in series with a led, power or P= 4.79w.
When a voltage of +64v is applied across a resistor of 3k ohm connected in series with a led, power or p= 1.29w
Also I understand (correct me if I am wrong) to maintain the same current through a circuit when the voltage is increased, the resistance has to be incresed which causes power of the resistor to increase along with the heat quite so much as to melt the resistor (assuming resistors used are 1/4w power).
Now my question is : 1. Neglecting current needed by led, why doesn't the 10 ohm resistor melt or heat up (I tried it practically with a 9V battery) ? 2. Why doesn't the led burn practically when I connect it to the 9v battery as the simulator shows 692.16mA?
