An arc welder provides 250 amps of current when operating with a voltage of 40 volts. what is the power required by this welder

Power = VI

Where V is the voltage and I the current

P=40*250

=10,000 watts

=10 kilowatts

The power (P) of the circuits is the product of the voltage (V) in volts and current (I) in amperes.

P = IV

Substituting the known values to the equation,

P = (250 amps) x (40 volts) = 10,000 Watts

Thus, the answer is 10,000 Watts.
