The power rating (P) of a device can be calculated using the formula: P = V x I, where V is the voltage and I is the current.
Given that the power rating is 1440 W and the current is 12 A, we can rearrange the formula to solve for V:
V = P / I
V = 1440 W / 12 A
V = 120 V
Therefore, the voltage required for the power tool is 120 V.
