Question

a welding machine is set to produce 24 volts and 150 amperes.
what is the total power output (wattage) of the machine? ($p = vi$)
6.25 watts
174 watts
3600 watts
36,000 watts

Explanation:

Step1: Substitute values into formula

Given \(P = VI\), \(V = 24\) volts and \(I=150\) amperes. So \(P=24\times150\).

Step2: Calculate the product

\(24\times150=(20 + 4)\times150=20\times150+4\times150 = 3000+600=3600\)

Answer:

3600 Watts
