How hot will a resistor get
Web6 mei 2024 · The desired current flow for a typical 5mm LED is less than about 20 mA. 5v / 20 mA = 250 Ohms would be the minimum resistor value to use. Actually, that is incorrect, because the LED itself "drops" some number of volts, but forget about that for now, and just get the gist of: V = IR. Web2 jun. 2010 · I don't know the exact formula, but the power dissipated in a resistor is turned into heat. You would have to measure the power over time to figure out the amount …
