The ROV sub thread has me thinking about relays CONTACTS and how they are rated. When it comes to analog I do not get much past ohms law.
The contacts carry power so I think of that as P = IV
If that is correct a relay with contacts rated at 5A 24V could be used with 10A 12V.
If I am still on the right track what is one to think when no voltage is given for the contacts?
I know the voltage for the contacts are in regard to (also in regard to?) flash over between the poles. Or is it all to do with flash over and nothing about current? If so how can that be? Does P=IV not apply?
