Korrektur
der gute Patrick Leung von roadfly muss natuerlich sofort alles nachrechnen und hat anscheinend einen Fehler gefunden. Ich kopier das mal hier:
Heating element should have more resistance
May be the bulletin has a typo: it's more likely that the relay module to have 2-3 ohms and the heating elements to have 990 ohms. When 12 VDC is applied, current through the series connection will be approx. 12.1 milliAmp. Power to the heating element hence will be R*(I^2)=0.15 Watts, which IMO is still too low to give out any heating effect.
