Hi guys
I have a coil(solenoid) that has a resistance of 4.4 ohm. I am supplying it with 40V DC. Is it correct
that ohms law apply, 40/4.4 = 9 amps and 40*9 = 360 watts?
Also, the coil will be on for half a second or so, does this 'alter' the real-world needs in any way? Or
do I need a 40V DC 360 watts 9 amp PSU? If I have three coils(and they energize at the same time),
would I need to triple the PSU?
Thanks a lot!
