Resistors for a project, easy question!
This is an easy question about resistors, its been years since I use any.
So, I have a replay which is rate 12v DC and 2amp.
The power supply is 12v DC and 6 amp.
V = I X R
R = V / I
so R = 12 / 2 = 6ohm
So I need a 6ohm resistor? Is that correct?
I can't believe I have forgotten this!
