A power tool uses about 12 A of current and has a power rating of 1440 W. What voltage does the tool require

a 1552 V
b 17280 V
c 120 V

1 answer

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.

c. 120 V
