~~The ventriloquist goes to Heaven, the dummy does not.~~It won't make any difference. It's like asking "what will happen if I try driving a car that has a top speed of 100 in a 60 zone?"

What matters is how much current you've got going through the resistors (like how much weight you put on the accelerator)

The power consumption (Watts) of a resistor is I

^{2}x R, that is current squared (amps) time the resistance (Ohm).Current (I) is given by the voltage (Volts)

across the resistordivided by it's resistance (Ohm), so you can derive power = V^{2}/ RL
