I am doing the ohms law to light LEDs. I have misplaced the notes I had after a move. Can someone help?
I am going to be doing the following for 3 and 4 cells. Lighting up standard white and red LEDs. I can't seem to find my ohms law notes and I want to be able to configure the with calculation the value of the resistor I need to use to get the right current. The current is I think the 30-50ma range for standard stuff LEDs, but can someone point me to a primer again. I am probably just going to wire up some switches to run LEDs so I can make some simple night lights for my 2 year old and to put in some of his toys so the batteries last longer and give him something he can play again.
