The heat generated by a stove element varies directly as the square of the voltage and inversely as the resistance. If the voltage remains constant, what needs to be done to triple the amount of heat generated?

I need to know why this makes sense or not.

power = V i = V( V/R) = V^2/R sure enough

to triple the power at the same V, use 1/3 the resistance R

This can be done easily and very understandably by running three of the original Rs in parallel, like turning three stove burners on instead of one.
