special one because of the massive current or can I just live with

Wolfgang -

The most current you can get across the resistor is I = V/R = 12 / 27 = ~ .3333 Amp

The power in the resistor is P = I*V = 4 Watts

So you should try and find a 5 Watt Resistor. This will probably be pretty big.

Good Luck
