Hi
Just a quick one,
I am trying to figure out the current used by my nichrome wire.
Is is 50Ω per 1000mm (1m) - is this a normal ohms law thing?
im using 30mm
V=I×R
so re-arranged to find I would be
I=V/R
I = 12v/1.5Ω
So the nichrome draws 8Amps as a heating element. <<<is this right?
Will the resistance of the wire change as it heats up, I would like to switch it with a 10A relay.
Thanks
