The power is the product of Voltage times current.
If both are halved then the power after that is only 1/4 of the power.
If the voltage was doubled then the power would be quadrupled.
This “squared” relation between power, voltage and resistance is easily derived.
Given Ohm’s law V=I * R which also means I = V/R
and P = I * V
the P = V * V / R = V^2/R
Hope it Helps.
