*drags out physics*

OK, in parallel circuits, the total resistance actually decreases the more branches you add. (Weird, I know.) Ohm's Law then tells us that if you decrease the resistance, you increase the current. Then, we also know that power=I2R. So the amount of power you'd be drawing would decrease because you've decreased the resitance, but then increase proportionally the the square of the corresponding increase in current.

In conclusion, I think I've totally confused myself. In terms of safety/starting fires/tripping breakers...it would depend on the specs of the circuit, unless I'm totally missing something (which I probably am, so feel free to correct me.)
