Hi,
I have read through and I am still having problem understanding which resistor to use. Currently, I have created a simple circuit with a 12V battery producing 23A (stated on the battery) connecting to a 150ohm resistor and then to a LED. This works fine...
Now, my question is, if I change the battery to a 12V 60A (car battery), can I still use the 150ohm resistor or will the resistor overheat...? Do you take the Amp produce by the baterries in to the calculation...? How do you apply the fomular to this...? Please advise, thanks...
Regards,
Sim
