LED help. need calulations or advice etc?
Ok so I'm doing an interior LED project on my car. I need to know what type of inline fuse I need and what size so I don't burn out my leds.
Setup is this:
12v car battery->ilf->rocker switch->plate terminal->4 separate led series (in series). Each series has a 1ohm resistor. Each led is using 3volts and is outputting 20milliamps. Any help on calculating this would be appreciated.
Thanks
I'll stick with a 5-7.5 amp fuse. Since LED only use 3 volts of power and 20mA of currents. Its kinda hard to example but yea. 5-7.5 amps is enough. It shouldn't take more power than a radio and a radio use a 10 amp fuse.
