Current I flows through a conductor connected across a voltage source. Now the resistance of the conductor is reduced to half its initial value and connected across the same voltage source. In doing so the heating effect in the conductor will become:

Well heating effect is directly proportional to power. Power is v^2 /R so as resistance is halved power dissipated is doubled and so is heat generated

But power is directly proportional to R when resistors are connected in Series and your formula is valid only for resistors connected in parallel.
